Chord Progressions and Substitutions Jazz-reharmonization - Tonnie Van Der Heide-1

ABSTRACT

Reharmonization, also know as chord substitution, is one of the eternal subjects in personalizing thethousands of standard tunes and originals played by working (jazz) musicians and amateurs all over the world. Theauthor of this article examines the basis through intermediate reharmonization techniques such as basic chordprogression in major and minor tonality and their primary substitutions, substitutions used in Rhythm Changes,substitution as chordal embellishments, harmonized bass lines, harmonization of background melody line, andsubstitutions of jazz standards. The objective is to provide knowledge of reharmonization techniques associated withthe expanded arrangements and personalized chord progressions for the developing (jazz) musicians.

CHORD PROGRESSIONS AND CHORD SUBSTITUTIONS (ALSO KNOWN AS REHARMONIZATION) by Tonnie van der Heide

Most users of BiaB will at least have a basic knowledge of chords and some of their functions. It is this last

part I want to concentrate on chord progressions, how chords move from one to the other. These are also called

changes, which means exactly the same thing (changing from one chord to another).

There are some basic progressions that form the building stones of thousands of jazz and Broadway tunes.

Some are more popular than others. Most of them will last 2 bars, but there are of course longer ones. Here are some

of the better-known standard progressions in major key (Example 1-7). I have kept the first eleven examples, as you

may find them in songs in the key of C major and C minor. A more technical explanation of the progression in

example 4 is discussed at under example 12.

Example 1. Standard progression

*alternative solution 1.

*alternative solution 2.

Please note that there are many more standard progressions and they do not always start on the I chord,

just think of Satin Doll (Example 8).

Example 8. Satin Doll, bar 1-4, section A.

-3-

Or a bridge type progression (Example 9).

Example 9.

Here are some of the better-known standard progressions in minor key (Example 10-11)

Example 10. Standard chord progression in minor.

Example 11. Standard chord progression in minor associated with Autumn Leaves.

*analysis of example 11.

Except for the 7, I have avoided most color tones (9 th, 11th, 13th, natural, flatted or raised etc.), to keep

things as simple as possible for now. Color tones are also referred to extensions (of the basic triads) of a chord. It all

boils down to the same thing. This also means that any alteration of the basic triad; flatted 3rd, raised or flatted 5th are

not to be considered color tones.

BASIC RULES

The I chord can be moved to any chord, movements of other chords can be:

Chromatic: e.g. a dim chord always moves half a step up or down

In fifths: Am > Dm > G7 are all moves along the cycle of fifths

Diatonic (up or down along the scale): like | C / Dm / | Em / Dm / |

Change between two chords with the same root, but of different qualities, major to minor or vice versa, like

F to Fm (happens most of the time in tunes in major), or Cm6 to C7 (happens most of the time in tunes, or

part of tunes, in minor)

Symmetric movements, move a chord of the same quality and with the same color tones in equal steps up or

down, e.g. ascending in minor thirds | G7b9 / Bb7b9 / | Db7b9 / F7b9 / | or perhaps the most well-known is

moving up or down a dim7 chord in minor thirds

Any IIm > V7 progression can move to another IIm > V7 progression in any key. E.g. Satin Doll

The amen progression F > C or F > Cm

I have on purpose not included the so-called Coltrane changes, as I expect someone to write an article

about that and there are also many good books on the subject a.o. Coltrane A Players Guide To His Harmony,

available from Jamey Aebersold. The same goes for blues progressions

-5-

Lets put together the example one with the example fourth and the example 9 (bridge) and voil we have

some basic 32 bars of Rhythm Changes in C (Example 12).

Example 12. Rhythm Changes in C.

-6-

Lets take a closer look at bar 5 and 6 of the A part: Gm7 > C7 > F looks like a Vm7 > I7 > IV, while in

reality it is a IIm7 > V7 > I progression in the key of F (major), which means at this point the progression modulates

from the key of C to the key of F. In the bridge the changes modulate every two bars, as E7 is (in this case) the V7 or

dominant in the key of A (major), the A7 is the V7 in the key of D, D7 the V7 in the key of G and last but not least

the G7 brings us back to the key of C. These modulations have a decisive effect on which scale(s) one can use for

improvising.

There are of course many books on this subject too, for those of you who want to delve deeper in to this

stuff.

EMBELLISHMENTS

Having looked at some of the basic chord movements, let have a go and look at some embellishments. Themost basic form of embellishment is adding color tones that create a feeling of movement (Example 13).

Example 13. Chord progression embellished with color tones.

*basic chord progression

*embellishment

Or half step sliding (Example 14).

Example 14. Chord progression embellished with chromatic sliding.


*embellishment

-7-

Also any V7 chord can be preceded by its IIm7 chord (Example 15).

Example 15. Preceding V7 chord with IIm7 chord.


*embellishment

This leads us to a theory called minorization or majorization, where e.g. a V7 can be substituted for an

IIm and vice versa. A technique used a lot by the late jazz guitarist Wes Montgomery (Example 16).

Example 16. Yesterdays by Wes Montgomery, bar 17-18.

Here G13 is substituted for Dm. This means that improvisers can play G7 patterns over Dm and Dm

patterns over G7. If you take this one step further and substitute an Fmaj7 for Dm, you can play an Fmaj7 pattern

over a G7.

USE YOUR EARS

Now lets have a look at some substitutions. Beware that in some cases the melody and or bass line will

prohibit some of the following suggestions. Therefore always let your ear be your guidance:

1) A I major chord can be substituted by its VI minor chord, or C can be replaced by Am or vice versa.

This also goes for the IV that can be replaced by IIm (F > Dm) or vice versa.

-8-

2) A I major chord can be substituted by its III minor chord, or C can be replaced by Em or v.v.

3) Any V7 chord can be substituted by a IIb7 chord. This is also called the tritone (or flat 5 substitution).

For this substitution the embellishment rule a V7 chord can be preceded by a IIm7 chord, can work in three

ways!! The basic progression G7 > C can first be embellished to Dm7 > G7 > C (V7 chord can be preceded by a

IIm7).

Now you have (at least) three possibilities to make a substitution (Example 17).

Example 17. Possibilities of substitution of IIm-V7-I chord progression.

*original

*1st possible substitution

*2nd possible substitution

*3rd possible substitution

In the third possible substitution, we changed the Db7b5 back the original V7, while keeping the substituted

IIm7 of the tritone). If you have a closer look, you will see that this also explains the earlier mentioned half step

sliding.

The possible substitution solution to in minor (Example 18).

Example 18. Yesterdays, triton substitution used in bar 2.

*original chord progression

*substitution, Eb7 is the tritone substitution of A7.

ANALOGY

If chord tones are the letters, the chords are the words and the progressions are sentences. The whole chord

sheet (of a song) is the story.

PURPOSES OF REHARMONIZATION

Some people might argue: If it aint broke, dont fix it. In modern jazz though reharmonization is more

the rule, than the exception. So why do we reharmonize?

(1) To personalize a tune

(2) To get a bigger or thicker sound (more possible voices and density)

(3) To create variation (different chords, allow different scales)

(4) To harmonize a nice back ground

(5) To harmonize a strong bass line

As numbers 1, 2, and 3 are mostly self-explanatory, lets start with the last one.

-10-

HARMONIZED BASS LINES

A standard harmonized bass line (also known from BiaB) that can be used when a dominant 7 th chord lasts

for one or two bars (Example 19).

Example 19. Harmonized bass lines over dominant 7 th chord.

*original

*harmonized bass line

Or from Hallelujah I Just Love Her So (Example 20).

Example 20. Harmonized bass lines over partial chord changes of Hallelujah I Just Love Her So.

*original

*harmonized bass line

-11-

I have used the slash chords the same way they work in BiaB, in other words the note behind the slash is the

bass note. (G7/B = is a G7 chord, with the B as its bass note).

Of course you could do the opposite of harmonizing a bass line by letting the bass note remain the same

(called pedal bass, as shown e.g. in the Chord Options window in BiaB), while moving the chords (Example 21).

Example 21. Harmonizing a bass line by utilizing pedal bass.

*original

*harmonized by utilizing pedal bass

Even greater tension will be created by applying counter movement: the bass line descends, while the

melody ascends or vice versa. We will get back to this in example 29.

HARMONIZATION OF BACKGROUND MELODIES

If the reharmonized chords are two subsequent II > V7 progressions, and if the melody allows, you could

perhaps use a chromatic descending background melody to establish a new reharmonization (Example 22).

-12-

Example 22. Harmonized with chromatic descending background melody.

*original

*new harmonization by utilizing the chromatic descending background melody

This would bring us to the subject of musical short hand. Every progression has some built in little

counter-melody, which;

Can identify the progression and

Let you create instant skeleton arrangements.

I just mentioned that the short hand for | Em9 / A7#5 / | Dm9 / G7#5 / | could be F# > F and E > Eb, as

shown in example 22, which of course could be embellished in many ways.

For instance, some possibilities of utilizing reharmonization and its associated shorthand in the basic

progression are as followed (Example 23).

Example 23. Basic chord progression and its possible reharmonization with counter-melody.


-13-

*adding color tones and its associated counter-melodies

*adding more color tones and its associated counter-melodies

The biggest prerequisite for chord substitution is common tones in the original chord(s) and the substituted

one(s). The fewer common tones the more tension, the more common tones the less tension. Take the start of the

tune Misty by Errol Garner in the key of Eb as an example (Example 24). if you use the substitution shown in the

example 24, the only common note in the D chord in bar one is the melody note of D, which you will hear creates a

lot of tension.

Example 24. Common tones in original chord progression and its substitution in Misty, bar 1.

-14-

In every tune you will find one or more turnarounds, such as bars 7 and 8 and 31 and 32 in Rhythm Changes

(Example 25). Depending on the melody there are may variations, which also indicate some possible

reharmonizations. Usually you will find one long melody note at the turnaround.

Example 25. Bars 7 and 8 and 31 and 32 in Rhythm Changes.

*basic turnaround

Possible reharmonization of basic turnaround with G as melody line. Em7 descends chromatically to Eb.

From Eb to Ab and to Db is following the cycle of fifths. Db descends chromatically to C, and Db7b5 is also the

tritone substitution of G7 (Example 26).

Example 26. Possible reharmonization of basic turnaround with G as melody note.

Possible reharmonization of basic turnaround with E as melody line. Bb descends chromatically to A. From

A to D to G and to G is following the cycle of fifths. If you wanted to, you could of course substitute; Dm9 > G13b9

with Abm7 (or Dm9) > Db7b5 (Example 27).

Example 27. Possible reharmonization of basic turnaround with E as melody note.

Possible reharmonization of basic turnaround with C as melody line. Em7#5 contains the same notes as

Cadd9. The E descends chromatically to Eb and then we move along the cycle of fifths to Db, from where we

move chromatically to the I chord (Example 28).

Example 28. Possible reharmonization of basic turnaround with C as melody note.

-15-

A practical example of how one could reharmonize the Rhythm Changes in C, by the way Rhythm Changes

are almost always played in Bb at Jam sessions, so please learn this and the other progressions, in keys that are used

by you and others you play with (Example 29).

Example 29. Reharmonization of Rhythm Changes in C

*a variation/reharmonization of example 4

-16-

Variation is one of the reasons for reharmonizations, it allows different chords and different chord scales.

This is, according to me, one of the main drawbacks in BiaB. Once you have filled in the spreadsheet with chords,

the only variation you will hear, are the ones built into the style you are using. While, when listening to your favorite

jazz records, you will hear that the chords changes may differ from chorus to chorus and from turnaround to

turnaround, this is of course possible in BiaB, if you unfold the tune and then manually change the chords from

chorus to chorus.

LEARN SCALE AND CHORD INTERDEPENDENCE

As mentioned using different chords allows the use of different scales. Therefore I suggest you read one of

the many good books on the relationship between chords and scales from one of the many books on the subject, like

e.g. Jamey Aebersolds Scale Syllabus. Examples are the use of the Dorian scale over a IIm7 chord and the

Mixolodian scale over a V7 chord. But remember there are often more than one possibilities depending on the color

tones.

CHORDS ARE FOR ALL INSTRUMENTS

In closing I would like to mention that chords are for all instruments, also instruments that cannot play

chords!

So try to learn the progressions on a keyboard or guitar, even if it is just in the key of C.

Then try to learn those standard progressions in the keys that you normally use on your own instrument by

using the suggested shorthand melodies. Once you know these progression and their substitutions, you will be able to

learn (and remember) new tunes much faster and of course be able to improvise over them with more flair.

PRACTICAL EXAMPLE

Four reharmonized versions of There Will Never be Another You (first four bars only). The first two

examples come from a book by the late Dutch guitar player Wim Overgaauw, called European Jazz Guitar. The last

example is by yours truly (but others might have arrived at about the same reharmonization before) and will let you

hear a very chromatic bass line: Bb > A > Ab > G > Gb > F > E > Eb, which forms a nice counter-movement to the

melody (Example 30).

-17-

Example 30. Possible reharmonization for the first four bars of There Will Never be Another You.

ONE LAST WORD OF ADVICE

Remember that changes have their own rhythm. So changing chords e.g. every beat (lots of tension),

followed by staying on one chord for two bars or more (hardly any tension), is usually not a good idea, unless it fits

in with the melody, mood or arrangement. On the matter of density: you do not have to use all the notes in a chord,

leaving out a few can often improve its sound.

Here and there I might have used words like basic rules, always move up or down a half step,

prohibit etc. Remember that if something sounds OK to you, chances are that it that others will like it too. So nice

changes come first and the so-called rules are only there to explain why!

Now you should be ready to try some stuff on your own!

RECOMMENDED PUBLICATIONS

On the subject of reharmonization there are so many books that below you will just find a very small

selection. I have listed relative inexpensive books, ready available in most music stores and on the Internet. Many of

play-along books by Jamey Aebersold Jazz Inc. contain nice reharmonizations (They include CDs so you can

actually hear the accompaniment resulting from the reharmonization). Many of todays fake and real books also have

nice examples of reharmonizations. Some even give two or more alternative changes. It is not always necessary to

compare the reharmonizations with the original chords. As soon as you hear something nice or interesting, just try to

analyze how the changes have been put together and why they work in the actual situation. I am sure you soon will

be able to (re)use it in other tunes/situations in the future. Mr. Aebersold and Mr. Liebmans collaboration The

Scales Syllabus demonstrates the basic theory of chord scales, Mr. Ricker and Mr. Weiskopfs Coltrane, A Player

Guide To His Harmony demonstrates the harmony structure of John Coltranes Giant Steps and Countdown and its

extended uses, Mr. Aebersolds Nothin But The Blues contains information of blues riffs and blues play-a-longs,

and Mr. Jaffs Jazz Harmony demonstrates harmony and voicings with examples from known tunes.

ABOUT AUTHOR

Tonnie Guitar is my user name in the FSG. My real name is Tonnie van der Heide, born in Amsterdam, the

Netherlands and now living in Bergen, Norway. In the FSG I have contributed some reharmonizations of other

members postings and have posted some arrangements of my own as well.

My main instrument is the 7-string guitar and I do sing, mainly through my Digitech Vocalist Studio Ex, to

sound a little like a.o. The Four Freshmen.

I use BiaB for live jobs and for writing arrangements.

In order to let all the instruments from BiaBs output sound as good as possible I use two MIDI-sound

modules, one for the bass and one for all other instruments. On MIDI-channel #5 I output chords from BiaB to my

Vocalist (The bass voice goes into a bass amp, the rest a PA).

To accomplish this I use the MIDI-mapper in MS Windows 98, as this facility is not found in the newer

versions of Windows (XP & 2000).
