“Wild Ocean”: An Interview with Horatiu Radulescu

Bob Gilmore

This text is a much shortened transcription of an interview by the author with the composer HoratiuRadulescu, recorded in Freiburg, Germany, in 1996. The text preserves the unique flavour of Radu-lescu’s spoken English in an attempt to convey something of the multi-lingual nature of his thought.A secondary text has been added, made up mostly from statements by Radulescu himself and byvarious performers, musicologists and critics who have written about his music, to provide supple-mentary material illuminating further the issues that arise in the interview. The discussion centresaround Radulescu’s development of the “spectral technique of composition” in the late 1960s and itsapplication in his music.

KEYWORDS: Horatiu Radulescu, spectral music, microtones, sound plasma

In 1979, Olivier Messiaen called Radulescu “one of the most original youngmusicians of our time”, and the succeeding years have only confirmed his judge-ment. Born in Bucharest on 7 January 1942, Radulescu left his native Romania in1969 for Paris, where he began to explore harmonic spectra as musical materialand gradually evolved the principles of a new compositional technique in a seriesof works beginning in 1969 with

Credo

for nine cellos. Based on the idea of audiblyprojecting the activity and energy of the various partials of a complex sound, thespectral techniques developed by Radulescu (and the somewhat different “instru-mental synthesis” approach, also based on spectra, pursued by Grisey, Murail andothers from the mid-1970s onward) have taken root, and now seem among themost important exits from the serialist stranglehold on contemporary music (see


,

19(2,3)). Radulescu regards his spectral techniques as“a conceptual reply (two thousand years later) to Pythagoras, and a realization ofthe intuitions of both Hindu and Byzantine music, which were the closest tonatural resonance”. He has developed these techniques significantly in thedecades since.

This text is based on an interview with Radulescu recorded in Freiburg,Germany, on two frosty days in early April 1996. Although some of my questionsnow strike me as naïve, I have resisted the temptation to “improve” them, as theymay not be too dissimilar to the questions of others coming relatively new, as I wasthen, to his music. In presenting the interview material here, I have chosen topreserve the unique flavour of Radulescu’s spoken English as transcribed from mytapes. This is not from a belief in verbatim transcript for its own sake, but from a

wish to convey something of the multi-lingual nature of his thought. Radulescu isfluent in French, German, Italian and English, besides his mother tongue, Roma-nian: he speaks a particularly articulate form of lingua franca English, that attrac-tive foreign cousin that is the language in which most of the affairs of new musicin continental Europe today are conducted. The interview is greatly shortened butotherwise only lightly edited. To it I have added a secondary text made up for themost part from statements by Radulescu himself and by various performers,musicologists and critics who have written about his music. This supplementarymaterial offers glosses on, or more precise information about, some of the issuesthat arise in the interview. The resulting biphony – between informal and formalvoices – is intended to stimulate further discussion of Radulescu’s fascinatingoeuvre.

BG Do you like to answer technical questions about your music?

HR It’s good to tell and not very good to tell [

laughs

], because they can’tcompose as you, the others, this is the problem. I like to explain, very much,as sometimes Stockhausen did very well. I said earlier that Ligeti liked verymuch my fourth string quartet with the Ardittis: there was a nice lecture bya German guy from Freiburg, Hartmut Möller, and Ligeti was there, and hesaid it’s too

savant

, I don’t understand what it means exactly in the spectral.I like the music very much but I don’t understand the scientific approach.Because he likes clustering with microtonal intervals and so on, but henever knew exactly the spectral technique, I think. The single one whomaybe knows a bit more about this is James Tenney. No? I think he’s themost strict.

BG He’s certainly been very concerned to theorise in a formal way about thewhole issue of tuning and harmonic perception.

HR But with James Tenney I find his music is sometimes too theoretical, it’s likea theorem, like a demonstration of a theorem in mathematics. It’s not totallymusic, you understand? It’s like a very beautiful theorem. No? Like

CriticalBand.

But is this music, or only the beautiful demonstration of a theorem?Which is nice, also! It’s very clean, very serious and very poetical also, to bevery pure like that. But if it has the power of an artistic work, of an oeuvre,you know, I’m not quite sure. Not always. Some of the pieces, yes. I prefer tohave the theory and the theorems and everything and then to forget them,and to make a fantastic, devilish music. And in this sense I feel more healthy,and more like a composer than a speculative mind.

Radulescu’s works are built from sound situations created by different treatments of fundamentals, thespectra produced by these treatments, and the isolation of individual spectra. The music results“naturally” from the initial organisation of sound sources and formal structures, its interest lying inthe interaction of the resulting harmonics, difference tones, subtones, rhythmic beats, and so on. Thetexture thus produced is called the “sound plasma”. (Heaton 1983: 23–24)

. . . Because there are two big traditions, one more speculative, one morecreative, you see? And I think that the composer should be an actual creator.If you are more speculative you are more scientific. But I appreciate Tenney alot. Also I appreciate Alvin Lucier. I think they are the best in America, thesetwo. No? Alvin Lucier created a lot of spectrality with his piece on a wire.

BG

Music on a Long Thin Wire.

HR Yes. It’s creating spectra, revealing spectra from nothing, because if youcompose like that – with frequency components of spectra and emancipatingthem up to nearly actual instruments – you have mixtures of nearly orches-tras, creating from themselves these generative functions. You excite yourbrain with these in order to listen to other functions which are not present,but which respond to the rule of ring modulation. You see? It’s nature.Therefore it’s very healthy and very non-dissonant.

NATURE and ART in their highest degree of purity merge. Therefore the sound plasma as music ofthe sign FUTURE should reach an abstract nature, created by us, which conceals – as nature does –both cause and effect, and thus surpasses its original condition (“handmade”) by becoming a complexphenomenon. (Radulescu 1975)

BG Although your own music is very radical in its technical aspects, and its soundis very new, nonetheless the great love you obviously have for the wholetradition of western music always comes through in your work. That isdifferent than some of the American composers you’ve mentioned, whosometimes seem more ambivalent in their attitude toward European tradition

.

I was struck, for example, by the dedication of your

Das Andere

, “to PatrickSzersnovicz for his Brahmsian soul”.

HR For me the most important is to be very close to, for example, Josquin DesPres, because you have the feeling of a fresco; you forget the technique andyou get into a special atmosphere, a special state of sound which is much more– as in the sense of Xenakis – a metropole of small elements into a big mass.Clouds of polyphonies, and so on. Or by Tallis also, no? It’s very beautiful.You have to work in this sense today with new means. To create a big fresco,a Leonardo in sound. Why not? But of today. Maybe more crazy, like natureis. Like the ocean. What we see today – it’s sometimes more crazy. From theplane, when you see the whole ocean and whole clouds. Leonardo onlyimagined this. In this sense you have more freedom also.

Clouds change colour, form and sky position mostly imperceptibly. Gaining and losing stars in the lateevening and before dawn, we cannot determine a precise instant for it, and we enjoy a ‘trembling time’feeling. (Radulescu 1975)

. . . I have to say not only do I adore the western tradition but also I think thatspectrality is a global way of including also the Byzantine and Indian music.They felt in their subconscious the direction of it, this tendency toward spec-trality, because they were impressed by the sound, its resonance under vaults,or by the sympathetic strings on the instruments. This spectral language, Ithink, integrates the whole tendency of Byzantine and Indian music, becauseif you analyse the old Indian music and the Byzantine you feel that they aremelodically very spectral, or very proto-spectral. I think it’s the tendency ofmany cultures of the world to be as close to the sound as possible, to the secretdeep structure of sound, which is spectrality. No? But I don’t like to call themusic “spectral music”, I like to call this technique of composition the

spectraltechnique of composition

. The music should have no

étiquette

. Just music.Because it is enough to be called only music. So when they call it “spectral


108

Bob Gilmore

music” or “stochastic music” or “serial music”, that’s their problem. I don’tlike this type of

étiquette

.I think many cultures were close to this, even the Japanese – I’m very fond

of some Japanese temple music and so on – and also Chinese and Korean andVietnamese music and Balinese. Also African music. But we should not inte-grate them in music as a gadget, in the way that was in vogue even in the ’60sby Stockhausen and other people. They just brought them to our

vitrine

, no?“Oh look how nice, I know also a bit of Bali.” It’s not good. I think with thisvery global language of the spectrum, you can be somehow close to sometendencies in those musics . . . but this orient/occident opposition, or sellinggadget, I felt was not very nice. Not very elegant. It’s like importing/exporting. It’s not fantastic.

BG Airport ethnic

.

HR As we are today: being in India now, or being in the States now, or being in,I don’t know where, in Japan and then in Chile. Somehow. But we stay in thesame plane. You see a bit of the Fiji Islands.

BG Do you see, then, the spectral technique of composition as a natural evolutionfrom the ongoing history of music?

HR Yes. I try to be very logical in its functionality. From the Byzantine modes,from tonal music, from serial music, I don’t throw away anything from thetradition.

Masked behind sometimes rowdy declarations and almost creating a new language by placing in thesame melting pot English, German, Latin, Italian, French and Rumanian for the titles of his pieces,Radulescu converses across time with Pythagoras (

Pythagoras’ dreamings

, 1972), Mircea Eliade (

Taaroa

,1968–69), Shakespeare (the quartet

Infinite to be Cannot be Infinite, Infinite anti-be Could be Infinite

, 1976–87), and Lao Tzu (Piano Sonata No.2, “Being and non-being create each other,” 1990–91, and PianoSonata No. 4, “Like a well . . . older than God,” 1993). (Mallet 1996)

. . . And because of it, like Schoenberg said, you climb up the spectrum, evenfurther . . . with Wagner and Scriabin and so on, no? From Machaut andJosquin and Monteverdi, you’re climbing further up the spectrum.

BG I’m interested to know what music you knew and felt closest to back inRomania.

HR Oh, we studied very seriously, with Stefan Niculescu I studied analysis, andWebern a lot. I finished my exams with some scores by Webern andStravinsky, the last period –

In Memoriam Dylan Thomas.

We analysed verydeeply Bach and Schütz and Monteverdi and Gesualdo and so on. And a lotof Webern.

BG Do you agree that Webern’s music is dependent on the tempered scale, ontempered tuning? Because it seems to me he’s the first great composer whosemusical thinking is completely tied to 12-note equal temperament.

HR Yes, yes, but he’s, let’s say, at the edges of the sixteenth, fifteenth, seventeenthharmonic, you see, with the semitones. So the most tensed possible relation.And using the isomorphy of the other tones, but in the most advancedlanguage which he used.



109

The overtone series must be regarded as, practically speaking, infinite. Ever subtler differentiations canbe imagined, and from this point of view there’s nothing against attempts at quarter-tone music andthe like; the only question is whether the present time is yet ripe for them. But the path is wholly valid,laid down by the nature of sound. (Webern, lectures in Vienna, 1933. Webern 1975: 15)

. . . Webern was also very economical, fantastic economy, with the rows some-times being nearly the same form in reverse, or inverse, and so on. He usedfrom all the possibilities a very narrow amount.

BG Do I take it, then, that you don’t see the Boulez-Stockhausen way withserialism as being the only legitimate continuation of Webern? Do you feel it’sa distortion of Webern, of the beauty of his music?

HR Yes, sometimes it’s a very big

hypertrophia

of Webern in a bad sense, like acancer on an organism. A beautiful organism, of the stellar beauty of Webern.He’s the most advanced from the three Viennese. Let’s say the purest. Also inSchoenberg and in Berg you have pages very related to this. But Berg is morea return to Romanticism, no? It’s very Romantic, very rich polyphonically,very beautiful. In the

Six Pieces

by Schoenberg I found also very many things.Schoenberg was a fantastic composer. And his

Verklärte Nacht

is forty-fiveyears earlier than

Metamorphosen

by Strauss, thus very in advance of its time.And the “Farben” is fantastically new; he’s nearly “plasmatic” in the“Farben”. Harry Halbreich told me, “Schoenberg is your grandfather, andScelsi your father!” It’s true. And maybe an uncle is Ligeti.

Fighting against what he calls a “discontinuous and manufactured music” and the “acrobatics of thepost-war period and its post-serial waste products,” the composer is “partisan,” on the contrary, tomusic based on “energy operating within a sound that is as continuous as possible” – in the lineage ofGiacinto Scelsi and György Ligeti. (Mallet 1996)

1

BG Do you feel a kinship with Varèse, with his interest in timbre?

HR Also. Varèse is a very

fauvistic

way of playing with the sound source directly.Nearly each sound is so powerful and intense, also like a star. But maybe themost pure was Webern.

I think the generation of Boulez and Stockhausen is a lost generation, inbetween big trends of the

Kunst.

They change all the time their skirts, theirjacket, they do not believe in one way. Boulez is believing so much in the serialscale of twelve that the whole history of music for Boulez was only onmillimetric paper, whereas the spectra are on logarithmic paper; the distancesbetween the sounds are measured on logarithmic paper. This is my invitationfor everybody, to agree to the natural model. Which is logarithmic. And I thinkthat some Indians and some Byzantine, they were very close to this, intui-tively. Even if they do it in another way, they divide the octave in seventy-twoor sixty-eight and they take twenty-two or eighteen.

BG When did you first get interested in Byzantine music?

HR Oh, we have been a bit Byzantine always in Romania, but it’s more from ourtraditional religion. The Byzantine monks notate it with special signs. Andthey use microtonal alteration of pitches, very scientifically, with a totallyother type of approach. And then, the melodic way of treatment, the verybeautiful and rich melismatic technique of the Byzantine is very impressive.


110

Bob Gilmore

When I travelled to Athens I heard incredible Byzantine chants, totally old, inthe churches; in Romania it comes back into existence now. But in Greece youstill have a great tradition. It’s very beautiful how the monks, you know, veryascetically enjoy the sound. And that could be very religious and verymystical. But I think always they get very near to the resonance of thecranium, and of the space.

Radulescu’s mystical approach to composition is, perhaps, a throwback to the sixties. . . . But whateverits origins, his work offers an alternative to the regression and conservatism of the neoromantics, theoften impenetrable complexities of the post-integral serialists, and the mindlessness of much mini-malism – a refreshingly different music which is both “musical” and new. (Heaton 1983)

. . . I did myself a composition with more-or-less improvised monks’ tech-nique in some Romanesque churches in France, and I called it

Aulnay Mass

.It’s like a monk singing, but he has forgotten from which religion he is. Andin some churches I got nearly five layers of voices at the same time, nearly,because of the big echo. It’s very enjoyable. So that was a nice experience, nearRoyan, in Talmont Romanesque church. I did then another version with three,with five, I did secretly a recording, a fantastic recording, where I nearly fellinto a trance of sound, the microphones were nearly on the bones.

The music we are composing is, above all, the music of a

special state of the soul

, and no longer a musicof action. (Radulescu 1985)

. . . And I have a version written up to seventeen monks singing at the sametime on a low A, but with many vowels and consonants, using a cloudytechnique of vowels with overtones, but avoiding nasal sound. The con-sonants change like mutes on the trombone – there is a chain of nearly twelveconsonants which you can smoothly vary.

BG You had already been developing the spectral technique from the late 1960s.

HR Yes, yes, from ’69. I think I was the first one.

. . . one of the most fascinating and original contributors to new European music. He was the foundingfigure in the Parisian “spectral music” movement, which extrapolated all kinds of new harmonicpossibilities from the upper reaches of the overtone series, and he has always been its most radical andintransigent exponent. (Toop 1999)

. . . I asked James Tenney when he started and he said in ’72. I said, “I startedin ’69!” [

laughs

]. Maybe Stockhausen had an intuition with

Stimmung

, but

Stimmung

was still very serial, because he took just different intervals, sevendifferent harmonics: the fundamental is only for the singers, on tape; then 2,3, 4, 5, 7, 9; it gives the fifth, the fourth, the major third, the tritone, and aslightly larger major third. In my opinion it’s a pity that it represents just thechord of the dominant ninth, for a work of one hour and twenty minutes.What is precious in

Stimmung

is the micro-spectrality of each of the six pitchessung, this spectrality being achieved by various vowels on the same frequencyplateau. This I use intensively myself and call it the “emanation of the imma-nence”. In my

Credo

for nine celli from ’69 I used the first forty-five harmonics.Nobody did it like that, I think, before.



111

BG And yet

Stimmung

always seems to me something of an exception in Stock-hausen’s output

.

HR Yes, and he was afraid of this, he said, “Oh, I’m at the limits of music.” No, itwas a gate to the future. And also

Sternklang

, after

Stimmung.

But he’s fromanother generation. He can’t compose otherwise than in a type of manufac-ture of the serialism, you see. He’s very obsessed by axes, is very Bartókian.He was much greater in

Gruppen

and

Carré

, no? Or

Momente

. Then he was abit retro-modal, in the

Indianerlieder

for example.

BG How did you become interested in the subject of tuning in general? Was itfrom your studies of violin when you were young?

HR Hmm, no, I had a Bösendorfer at home and sometimes I used it also as a

soundicon

, so called, bowing the strings with threads. It’s my idea, the sound icon:to go with a little bow, a V, like a ray, into a field of strings. It means you havejust one hair from the whole hair of the bow, threading it all around one string.Each string can be tuned differently. It’s maybe the richest instrumenttimbrally. And if you have a Bösendorfer you can get a miraculous resonance,and you are able to change all types of minute details of the sound, such as

ponticelli

,

tastiere

and so on, you have a lot of points along the strings.

The sound icon: a grand piano lying vertically on its side, with the strings played by bowing. Theinstrument is presented in a new light; it now resembles a religious object – a Byzantine icon. At a timewhen religion was only possible in Romania through music, I called this instrument the “Sound Icon”.Because I played violin myself, I was obsessed with the idea of reversing the proportion of the rolesbetween bows and strings. The problem was solved by reducing the bow to a single hair – in mostinstances, a very fine thread (diameter 1/10 mm). By describing a “V” around the piano string, thisrosined thread brings the string into vibration and causes all other open strings of the piano to resonatein sympathetic vibration resulting in a fabulous resonance . . . the tuning of the strings (

scordatura

) ofthe sound icon is specific to each score and strictly corresponds to the intervals determined by thespectral components (i.e. harmonic scales of logarithmic and thus unequal intervals). (Radulescu 1990)

BG Did you invent the sound icon in Paris?

HR No, in Romania, but in Paris later I called it the sound icon because it resem-bled the Byzantine icons, and also because it was on a

si

spectrum, a B natural(

si

in French or Italian), and I said “S”, “I”, oh, sound icon! You see? It was

ADoini

, for seventeen musicians with sound icons.

2

In Romania a shepherdplays with his flute a

doina

;

A Doini

is a verb which is more or less invented.It exists, however.

A Doini

is the infinitive, like

to doina

, to long with sound,as the shepherd does when he plays the

doina

for his love who is in the valley.And I introduced this instrument with this piece, where you have a compactspectrum between the eighth and the twenty-fourth harmonics, therefore ascale of seventeen different elements

.

3

Seventeen people are playing, each oneon just one pitch, but with a lot of processes, Freud/Jung processes [

laughs

].And also there are some false grandfathers of this spectrum, false fundamen-tals, very low. Instead of B natural there are B flat, A and C as false fundamen-tals, like big mammoths, projecting their own implicit spectra. The explicitspectrum of B natural is played more or less continuously, but those“thunder” spectra, random spectra based on the false grandfathers, are some-times also present. We built spider webs of nylon threads of different thick-nesses in between the pianos, because there are several sound icons, you can


112

Bob Gilmore

use as many as you like, even seventeen sound icons, big grand pianosvertically placed. You transport them without the lid, and you can see onlythe bronze and the strings. And sometimes you perform with rosined fingerson some of the threads, exciting more than one piano at the same time. Youget a tremendous thunder sound on the low strings and an “aura” on the finethreads of the high-register strings.

BG But you didn’t actually make this instrument public while you were still inRomania?

HR No, in Romania I was only a student. No, I did this mostly at home. Maybesince ’64, ’65, something like that.

BG I’m wondering where these sorts of experimental concepts grew from – boththe sound icon and the spectral technique itself – because presumably inRomania in the ’60s you didn’t have access to the most recent contemporarymusic from the West.

HR No. With the spectral tuning in Romania: before I left I phoned Stefan Nicu-lescu, one of my masters, and I said, “I have a fantastic idea, I will awake aspectrum of C on nine celli, up to the forty-fifth harmonic, like seeing a frescofrom nine different distances at the same time.” It means the first cello isplaying nine types of music,

alpha

,

beta

and so on; the second cello plays thesame fresco but from a nearer distance, so he has more time to look into thematerial, but he lost one type of music; and so on, the third will come nearerto this fresco, until the ninth cello is totally in the matter of sound, losing allthe other eight “musics” and being involved only in one. And so you getdifferent distances at the same time –– it could be related to the technique ofpainting on glass, you know . . . the old icons; because I had the idea also inpainting, to paint on different strata of glass. I did myself a bit of painting withcoloured China ink, but I gave this idea to an actual painter, not like me, inParis, and told him: “Why you don’t paint with three, four, five, nine glassesat the same time to get this type of special vision, like nine strata of stainedglass?”

This was the composition of

Credo

. And on this I phoned Niculescu, mymaster, and I told him, “Oh, I have a fantastic idea.” And then I left, next dayI left Romania in ’69. So the composition wasn’t totally ready but the ideacame already in Romania. It was, let’s say, in the air, maybe, an intuition.Because I was inspired also by the brass instruments, how they built every-thing from the low fundamentals. I had a sketch for a large orchestra piecestarting on a very low B flat. I didn’t know anything about

Stimmung

, but Bflat is very good for the brass instruments. So for my

Wild Incantesimo

I wantedto build everything on an enormous spectrum. In

Credo

I used nine celli;

WildIncantesimo

is for nine orchestras, with mostly invented instruments. InRomania, you express happiness by saying you are in the ninth heaven.

BG Earlier you mentioned Schoenberg, who invoked the harmonic series as a wayof providing a rationale for his use of dissonance. Does the idea of consonanceand dissonance, and especially their opposition, have any meaning for you asa composer?

HR There are tensions . . . dissonance and consonance are forces, maybe. If you



113

get into the idea of self-generative functions they abolish the notion ofdissonance, more or less. They have a degree of relationship, you know, ofbelonging to a specific “spectral family”; far away functions, and closer ones.

BG Do you agree with the point that Partch and Tenney and others make, that itis crucially important, the higher you go up the spectrum, to have precisetuning – that you need to have the intervals further up the harmonic seriesvery accurately in tune, otherwise their meaning is lost?

HR It is true, because there are more and more functions. It means the tuningshould be very precise all over. The intervals are more minute the higher youget on a spectrum, and if you are not precise you will lose much. For example,if you need a special sum and difference between functions, if you use thefifty-first harmonic, and you are too low, you will fall into 50, and 50 is thedouble octave of the 25, so you lost a lot of functionality. This is the problem.You have to be strict in order to achieve something. For example, I have 51;51 is the sum of 26 and 25. Twenty-six is the double of 13, and so on. But ifyou tune the 51 too low you will get 50, the double of the 25 already, so it willbe like an octave in Webern’s music, you understand? It will lose the sense ofa new function.

BG Very interesting. So this word “function” I now understand . . .

HR Functions, like dominant, subdominant, Phrygian second, and so on . . .

BG Yes, you mean “function” in more or less the conventional sense.

HR Yes. It’s a good sense to have. Because we use “function” in all languages. Wedon’t analyse enough this aspect, but I think music is done only by this forceof attraction between the spectral elements. It’s a family of self-generatingfunctions, a genealogy of pitch. And they are, let’s say, as filtered regions ofspectra, preferential situations of spectra. And if the music is very good andwell done, it reflects very profound harmonic laws, in the true sense ofharmony, universal harmony laws. I’m sure it’s like that. Composers from allages were close to these resonance laws.

I now discovered that in my

Das Andere

for viola I used for example theseventh harmonic on the first string, and on the second string I used theseventh up to the thirteenth, a melody, irregular melody, to be more or lessimprovised by the player against the seventh harmonic on the first string [seefigure 1].

This music sets out to create a state of trance close to that of a spiritual séance, through which one canevoke the presence of one’s “alter ego” or “higher self”. The very descent into the subconscious registerfacilitates the arrival of this psycho-acoustic phantom with the instrument’s continual spectral enrich-ment in its bass region. Two definite beings (alpha and sigma) experience their dialectic through theseven sections of the piece: . . .

arpeggiamenti

– “glimmers” of an obsessional voice (spectral bowing,out of phase), highlighting the chords resulting from ring modulations; Byzantine-spectrum biphony,using natural string harmonics up to the 20th, with

sforzandi

creating much lower difference tones.(Radulescu 1994)

. . . But all these harmonics are very consonant together. Why? Because theseventh harmonics on the second and first string, they make a perfect fifth, apure fifth like Pythagoras’s; that is, these open strings are like the second and


114

Bob Gilmore

third harmonic of D (the octave lower than the second string). It means all theharmonics I calculate on the second string are multiplied by two and on thefirst by three. It means my seventh harmonic on the first is not 7, it’s 21; andall the others on the second string are 14 to 26. Therefore, they sound verywell together, because the 21 belongs to the octave of 14 to 26. You see? Andthey give a lot of different tones if they are played on the violin, it’s incredible.If you have 21 with 22 you get in difference 1. If you have 21 with 26 you willhave in difference 5. It’s fantastic, the major third in the low register. Now I’mworking with somebody, and we listened exactly on the cello, the sum anddifference tones, especially the differences.

It’s fantastic.

[W]ith Radulescu we discover the physical division of the strings into their partials. In

Das Andere

,Radulescu uses these natural harmonics, up to the 20th harmonic; the piece begins with them. But healso uses other special techniques designed to “confuse” the strings by giving them contradictorysignals with the bow or the left hand in very quick succession or even simultaneously at times, andthis results in a breaking down of the sound into unpredictable “subparticles”, rather like a nuclearparticle accelerator!

4

BG Would you give some further examples of spectral functions in your music?

HR For example, a very beautiful chord with which I started the fourth stringquartet with the Ardittis, consists of the twenty-first and twenty-secondharmonics, giving in sum the forty-third, and in difference the first. It’s a typeof C (the fundamental) with three types of F. It’s very new music. It meansyou have three aspects of the same step, the F, against the C. In Hindemith,Bartók, Enescu and so on, you have the minor and major at the same time; orin Webern you have two types of fourths, no? But now you have three typesof the same function with the other function. If the 21, which is a low F, meets

22 (F half-sharp), it gives in sum a higher F, one octave plus one-sixteenth ofa tone higher. In other words, 21 and 22, in the same octave, give 43 in theoctave above. And 1 is the low C of the cello, the open string. How do youplay the 21 with the first violin? I play the seventh harmonic on the G (whichis like the third harmonic of the cello’s lowest C). Very easy. Irvine [Arditti]did the seventh harmonic on the G perfectly. What I did with 22, is a doubleof 11; viola on its fourth string plays the 11. The viola’s fourth string is alreadythe octave of the cello C string. You see? It’s fantastic. And only the secondviolin has to finger for the 43, with a bit of nail fingering, on the first string,an F a little higher, a sixteenth of a tone higher, and to play on it the perfectfourth artificial harmonic, to get two octaves higher, to get the F+. It’s thesingle pitch which is maybe not totally secure. If you have a bit of wind, or abit of, I don’t know, varying temperature, you will get this slightly altered.For this F, the nail fingering is meant like a new

capo tasto

. These threefunctions of the F against the C, I think, represent new means in the languageof music.

BG Could you tell me something about the

scordatura

used in your fourth quartet?I was trying last night to figure out the rather beautiful chart you reproducedin the programme booklet for the Arditti Quartet’s performance at IRCAM[see figure 2].

HR There are nine quartets, the live one placed in the middle of the public andthe other eight around them, pre-recorded. The central quartet is tuned to431 Hz in perfect fifths. The others are tuned spectrally, to simulate an imag-inary viola da gamba of 128 strings.

The idea of this opus initially came in the Loire Valley near the Clos Luce where Leonardo spent hislast years: a central string quartet (score

alpha

) surrounded by the audience which is surrounded bythe enormous circle of an imaginary “viola da gamba” with 128 strings (score

beta

– eight other stringquartets live or pre-recorded). That imaginary 128-string instrument uses a “spectral

scordatura

” of 128different, unique pitches corresponding to components of a C spectrum (C = 1 Hz) in between the 36thand the 641st harmonic. . . . The 49-minute composition realizes a polyphony/heterophony of twointerwoven macro-forms:

alpha

– 89 micro-music events of pulsating spectral “orbits” which modulatefrom and within 27 different spectra – like a voyage in between 27 different “solar systems”;

beta

– 137sound-mobiles which evolve on the 128 components of that unique spectrum of C – a “terrestrial”,dense sound-life. . . . The macro-form of music

alpha

depicts a global-register shape of mountain andvalley, i.e. uphill, downhill followed by downhill, uphill. It starts with a micro-music of 64”, irregularlyand constantly accelerating until arriving at the last micro-music of 4”. Meanwhile, the music

beta

appears and disappears – like tides of a wild ocean – in the middle and extreme high and low registers.(Radulescu 2001)

. . . I used a

scordatura

of 128 strings all differently tuned from a spectrumstarting from 36 Hz going up to 641 Hz. It means it’s easy arithmetically; ifyou take the fundamental as 1 Hz then all the other numbers are Hz – yourspectrum is easy to calculate. And I started with a nice octave, from the thirty-sixth harmonic (a multiple of the ninth). The cello is retuned down to a D (atone lower than the open E of the double bass). So the first octave is a verymodal octave of the C spectrum – D, the E a bit lower, F a quarter-sharp, G,G three-quarter-sharp minus (the thirteenth harmonic); then the fourteenth,the B flat a bit flat; and the fifteenth, the German H with a little minus; andfinally you get the C, the sixteenth harmonic. It means: 9, 10, 11, 12, 13, 14, 15

and 16. These are the lowest strings of the eight pre-recorded celli. It’s verybeautiful.

BG The example you gave a moment ago from the start of the fourth quartet,where you have three different Fs above a low C, implies that somehow thenotion of pitch class is still meaningful for you despite the heightened

precision of tuning. You still think in terms of the pitch class F, with differentshadings.

HR First we have a function of a subdominant or fourth, a little bit lower than thesubdominant, but in a sense more as a subdominant (the twenty-firstharmonic). Second, we have a neutral fourth, which is the eleventh (ortwenty-second) harmonic; and third, a higher fourth, which is the forty-thirdharmonic. There are three types of function, rather like the subdominant, thetritone and something in between subdominant and tritone. The

diabolus inmusica

was such a difficult interval because it was very near the eleventhharmonic, but not exactly that pitch.

BG This is a very exciting idea, because it means the idea of pitch class is thenbeing exploded into many different . . . I don’t know what the word wouldbe, different colours or different shades or different meanings.

HR But they are now functions. Maybe this is more difficult for us to judge becausewe are not used to them. They are like tritone and fourth before, but now thereare three types of F with the C. They have to be strictly in their registralposition, this distribution, following the principle of ring modulation. If yougroup them into one octave and make a little modus on a little synthesizer itwould be stupid, because they should stay at the distance they are.

BG To preserve the spectral logic.

HR Yes. For example, if I take another characteristic chord I use, the 16 and 21giving 5: you have the E a bit lower of the viola as 5, the so-called (in German)“little E”, a pure E (against a C); then you have the C of the soprano as 16, andthe F on the top line of the treble clef as the 21 (it’s a bit lower). If you putthem into one octave it’s rubbish. But like that, at these distances, it’s unique.I can even play it on the piano, it sounds not at all dissonant, because theelements (5, 16, 21) generate themselves. Even being a little bit false on thetempered piano, still they sound so healthy. And if you give this chord to somebrass instruments who can produce exactly the F on a G fundamental, as theseventh harmonic or the fourteenth, and the C is played on a C fundamental,and E on the tuba as the fifth harmonic of a C fundamental, you get totallyprecise tuning. And it sounds completely accurate. They generate themselves.If 5 meets 16 it gives in sum 21; 21 and 16 gives in difference 5. You might alsoconsider the virtual existence of the eleventh harmonic, which will be gener-ated by 16 and 5. This whole self-generative process is a deep structure ofbeauty. I have a whole piece made only on these two chords, from one chordto the other.

BG What is the piece?

HR It’s a very conceptual piece I did, Sereno, just moving from one chord to theother. It means from 5, 11, 16 to 5, 16, 21 [laughs]. Just this. Like a horizontalsand clock, you see, for these two chords. I have some pieces like that, whereimprovisation is very important. Also my Clepsydra uses this macroform of ahorizontal sand clock with the transmutation of a G spectrum into a Cspectrum via a common function, D, which is the third harmonic in onespectrum and the ninth in the other.

BG I notice similar sum and difference principles in your recent piano sonatas.The opening of the second sonata is built on the spectrum of a low B flat, thebottom B flat of the piano: the 4-note chord that occurs in the first threemeasures could be analysed as 10 and 11 (D and E) giving in sum 21 (E flat)and in difference 1 (B flat); in the fourth measure the fundamental haschanged to C, with 5 and 16 (E and C) giving in sum 21 (F) [see figure 3]. Itseems surprising, given your obsession with spectral scordatura and withmicrotonal pitch systems, that much of your most beautiful recent music isfor the piano.

HR But I would say these sonatas simulate, with the equal-tempered scale of thepiano, very new harmonic, heterophonic, polyphonic and monodic structurescreated by the self-generative spectral functions. For me they retain the splen-dour and the wild purity of these pitch materials.

In more recent works he has incorporated themes from folk music, but without abandoning either hisstructural rigour and inventiveness or his mystical conceptions . . . [the fourth sonata] is linked throughnumerous elements to the Piano Concerto op. 90, which seeks to gain entry to the world of the magical,the “inner Universe”, through the tension between ring-modulated spectral functions and the folkmelodies of our ancestors. (Möller 1997)

BG Do you have any interest now in writing theoretical papers, or do you feelyou’ve done that and have said what you wanted to say?

HR I think it’s better writing explanation to the pieces, it’s more practical. It’s niceto write theory. Sometimes it pushes you. It pulls the theory to the practiceand vice versa.

BG Could I ask you about your little book, which I was reading this morning,Sound Plasma: Music of the Future Sign. This is now over twenty years old. Howdo you feel today about the text and the ideas in it?

HR Oh, it’s still good. It’s both a prose composition and a theory text. The textwas written more or less in ’69/’70 and then improved in ’73, and publishedin ’75 by Edition Modern in Munich.

BG The idea of the “sound plasma” – do you still think in those terms in morerecent pieces?

HR In a way yes, because it’s a very vivid matter of sound.

For Radulescu, the notion of “sound plasma” also implies an almost neo-Boethian distinction between“planetary” and “cosmic” music. It is this aspect – in many respects akin to Stockhausen’s outlook –that most clearly distinguishes Radulescu’s music from the “instrumental synthesis” (also spectrallybased) pursued by composers like Grisey and Murail from the 1970s onwards. While the lattercomposers’ work is in some respects scientific and clinical, expounding clear acoustic processes,Radulescu’s aims are essentially spiritual and magical, drawing not only on Catholicism but also onDaoism (in particular, Laozi’s Daode jing). (Toop 2001)

. . . It means if you use from the sound spectrum some cells and you changethem into fundamentals and you play on them with very rich, or enriched,techniques, you make a very timbral and dynamic, very vivid sound. Youcreate a sound plasma. Like here [see figure 4], this is the global space of thesound, and these are the global sound sources; I wanted sometimes to have

all of them used or just one, simulating the other ones, enriching itself. So myaim was at that time to conceal the cause and the effect. As a matter of fact,you have three types of global sound sources: the “inside” source, singing orreciting and so on; the “tangent” source, which is the instrument, electronic,digital sound; and the “outside” source, out of yourself, it means naturalphenomena and so on. And this was an aim, at that time, to make everythingfluctuate and thus reach a new state in a subconscious way. But later I furtherdeveloped my spectral approach, by using very precise orbits of pitch, corre-sponding to spectrum components, like planets in a solar system.

BG What do you mean by “orbits”?

HR The components of a spectrum are very precise in pitch, like plateaux offrequencies. On them we can create a new micro-spectrality. I call this process

“the emanation of the immanence”. Sometimes this process is very complexand you can confuse the roles of fundamental and spectrum components. Butyou can emancipate a cell of a spectrum into a new fundamental. Sound Plasma

was a theoretical text with poetry all over. It’s between science and poetry.And later I wrote another text, in French, which is a bit more advanced, in1985.

BG “Musique de Mes Univers”.

HR It gets into each score a little bit, like what I would like to have some day ina big volume, much more developed for each score. I think it’s the best idea,to treat each score, each little window on my universe, like it is.

BG Whereas this Sound Plasma text is more general, more theoretical.

HR But it was a very early text. I used it in Flood for the Eternal’s Origins from Parisin 1970, also a very conceptual score.

In 1969–70, with opus 11 Flood for the Eternal’s Origins, we concluded that it was necessary to “enterinto” the sound, to rediscover the ocean of vibrations that Pythagoras scrutinised two thousand yearsago. (Radulescu 1985)

. . . We performed it in Darmstadt in ’72. It was the first time I conceived ascore using “global sound sources”: you see, I/O, instrument or object played,it means for example violoncello or tam-tam; H, the human source, a vocalsource, singing, whistling; E, an electronic source; and N, natural phenomena.

BG Were you already interested in Zen Buddhism by this time? Because thingslike the idea of concealing cause and effect that you speak of in certain earlierscores (for example in Capricorn’s Nostalgic Crickets) sounds a bit Zen.

Seven flutes move along a “square well” of ninety-six sounds – an “infinite” melody enclosed in a circleand made from inharmonic pitches (quartertones). . . . Four types of playing technique (“vie-timbre”)activate the micro-spectrality of each sound:

1. yellow tremolo (“morse” signals of different fingerings on the same pitch),2. stable multiphonics,3. unstable multiphonics, overblowing producing “spectral thermometers”,4. flutter-tonguing a note and singing in unison simultaneously.

(Radulescu 1993)5

HR God doesn’t say exactly from which type of molecules he makes the beautifulcolours of a cloud. I feel we should do the same: conceal cause and effect, inorder to obtain a fantastic phenomenon, which would be as beautiful aspossible. It’s like an invasion of beauty. I think it’s a type of joy, of special joy.It can be a mystic joy. The first movement of my Piano Concerto The Quest Icalled “The Gate”, like the gateway to the universe.

The listener is transported in a universe out of time, made of interrogation, mystery and contemplation– until reaching the light. (Sabbatini 1998)

. . . It can be the inner universe or the outer universe, it’s like being on . . . inFrench you say “sur le seuil de l’univers”, you know, just on the threshold ofthe universe. We don’t know which one. It’s your own inside, or the wholeuniverse. It’s like getting a bit of the power of God, you see, for yourself. It’slike a mystical experience. But in a very poetical way, not at all in a guru sense.It’s more, let’s say, authentic poetry. I’m very impressed by Lao-Tzu, verymuch, by the Taoist eighty-one poems. But if you read Lao-Tzu, “being and

non-being create each other”, it’s nearly modern physics, matter and anti-matter, you see. It’s a fantastic intuition he had.

The post-serial composers liked mostly ugliness and destroyed things afterthe War. And I hated it, because I have no complex of the War. I was born in’42, so I couldn’t judge everything through the War. And I was more optimisticthan Boulez and others. It’s normal. I am from another generation, I try tocreate beauty. Why not? They were afraid of the term beauty, it was . . . likein Fascism, it was an interdiction of using beauty as term. Everything had tobe, you know, kaput, zerbrechen, broken, like a big amount of rubbish andanguished things. Why not believe again in beauty? Beauty as harmony, thesingle way to save the society from all the wars that are still keeping on. So ifyou believe in beauty and you propose it as a magnet, attracting humanbeings to other aims than wars, you give some hope.

Coming from and going towards THE ETERNAL (the outer time) the music CREATES into the time AMAGIC STATE OF THE SOUL. This is its single aim and reason to exist. (Radulescu 1975)
