Definition
A composition technique that
features the use of all 12 tones
(musical notes) of western music
without creating any sense of tonality.
Composition Process
Generate a
succession of 12
notes without
repeating any
Apply Inversion,
Retrograde, and
Retrograde-Inversion to it.
Create a matrix of 48
possible melodies with
these four series
Serialism
Inventors
Karlheinz Stockhausen
Pierre Boulez
Definition
The idea of generating a series and
manipulating it through composition
techniques was extended to other
elements of music: rhythm, dynamics,
expression, and attacks
Extended Tecniques
The use of a musical
instruments in ways that it
wasn’t conceived to be played
Prepared Piano
John Cage
Inserting different objects
between the strings of the piano
in order to make it sound more
undetermined and percussive.
Minimalism
The use of the least musical
resources as possible to
compose music
Steve Reich
Relies on the use of slight
differences in tempo between two
identical music parts to play with the
brain’s ability to differentiate sounds
from each other
Concrete Music
Electroacoustic music style
Recording sounds from the
environment and manipulating
and organizing it with the help of
electronic devices
Symphony for One Man Alone
Pierre Schaeffer
Electronic music is music
generated entirely electronically
Initially developed by the military,
and given to the public when they
became old.

Pulse Generator
Amplification

Arnold Schoenberg was worried
that musical chaos would occur
Invented twelve-tone system
Would use transposition, later named serialism
Became basis for experimentation
Students Berg and Webern
later further developed it
Minimalism (p. 75)
Originated in 60s
Opposite of complex
intellectual approach of
total serialism
Based on repeated
melodies, harmonies, and
rhythm. Almost hypnotic at
times.
Central Figures
La Monte Young
Composition #7
Terry Riley
In C
Made up of 53 music fragments
Performers would choose

Steve Reich
Philip Glass
New Sounds (p. 76)
Performers learned to play by using the instruments in
ways they weren’t invented to be played such as
slapping the strings of a guitar, plucking them too hard,
or producing animal sounds instead of just blowing air
Electronic Sounds (p. 77)
New Technology
Late 40s and 50s =
magnetic tape
Musique Concrète
Étude avec chemins de fer
Pierre Schaeffer
Synthesizer
Could produce and
modify sound as well
MIDI (musical instrument digital interface) was
adopted which meant that electronic musical
instruments can communicate with computers
“Electronic music has moved from a studio
full of electronic equipment to the home
computer, within reach of everyone.”
