History & Backgroundof Set Theory
David Smith 100022110
Origins for Set Theory (MATH)
Father of Set Theory & Combinatorics Georg Cantor (German Mathematician)– created it in 1874, – Although it was more stictly defined over time
up until 1897
Mathematical Background
Math and Music - Hand in Hand?
Set Theory began through 12-Tone Music– by Arnold Schönberg’s 12-tone techniques– by Josef Hauer using his theory of ‘tropes’
Both use Math largely for determining matrices and tone rows, thus the beginning of math in music
– by Anton Webern in composition (1930s) as well as Leibowitz, Rufer, Perle
These are the basic math concepts which are applied to Set Theory later
But, where’s the Set Theory?
The theory of Hexachords was then presented by Rochberg in 1955– This idea did not cover all of set theory, but more
than before– Defined chords by a set
which was a list of the pitch classes in the chord
Boulez also made statements towards the musical techniques with math and music
Finally... Set Theory
Proper formulation of set theory of music only followed the theory of hexachords– Milton Babbitt, Donald Martino, David Lewin
and John Rothgeb created it around 1955-1960– They used the formation of groups, harmony,
functions for melodies and rhythms in 12 note music and interaction of these over time.
These were still only compositional methods using set theory
THE TRUE SET THEORY
No actual Analysis of Set Theory was derived until 1964
Most significant contribution - Allen Forte– extended notion of pitch-class set– association of sets
‘setcomplexes’, ‘subcomplexes’ ‘complex’ - the relation by inclusion to central sets
What did this do to Analysis?
These concepts established organization – giving analogies to tonality
Brings tonal coherence to large-scale music structures and the links between sections
With this theory Forte was able to analyze many atonal works:– Berg, Schönberg, Stravinsky and Webern
Computers take it to a New Level
With the use of computers, Forte easily compiled a roster of complexes
Created syntax's for analysis of compositions by use of a computer– each syntax can be formulated for
compositional style of composers
