Karlheinz Stockhausen was a German composer, widely acknowledged by critics as one of the most important but also controversial composers of the 20th and early 21st centuries. Another critic calls him "one of the great visionaries of 20th-century music"...

.

Beginning in the early 1960s, Stockhausen composed several instrumental works which he called "process compositions", in which symbols including plus, minus, and equal signs are used to indicate successive transformations of sounds which are unspecified or unforeseeable by the composer. In these compositions, "structure is a system of invariants; these invariants are not substances but relations.… Stockhausen's Process Planning is structural analysis in reversed time-direction. Composition as abstraction, as generalization. Analysis of reality before its entry into existence" (Fritsch 1979, 114–15). These works include Plus-Minus (1963), Prozession

, before returning by the same path.

For Reich it was important that the processes be audible: "I am interested in perceptible processes. I want to be able to hear the process happening throughout the sounding music.… What I'm interested in is a compositional process and a sounding music that are one and the same thing" (Reich 2002, 34). This has not necessarily been the case for other composers, however. Reich himself points to John Cage as an example of a composer who used compositional processes that could not be heard when the piece was performed (Reich 2002, 34). The postminimalist David Lang

Within the field of popular music, process music made its strongest early appearance in the ambient

. On several of the tracks of this album, musicians were instructed to play a small section of Johann Pachelbel
Johann Pachelbel
Johann Pachelbel was a German Baroque composer, organist and teacher, who brought the south German organ tradition to its peak. He composed a large body of sacred and secular music, and his contributions to the development of the chorale prelude and fugue have earned him a place among the most...

's Canon in D major in different ways. On one piece, for instance, musicians played the section at different speeds, the speed determined purely by the pitch of the instrument used. Thus the bass instruments played the section at a slower rate than the treble instruments, and the new piece created was shaped by these melodic lines drifting in and out of phase with each other.

Theory

Michael Nyman has identified five types of processes (Nyman 1974, 5–8):
  1. Chance determination processes, in which the material is not determined by the composer directly, but through a system he or she creates
  2. People processes, in which performers are allowed to move through given or suggested material, each as his or her own speed
  3. Contextual processes, in which actions depend on unpredictable conditions and on variables arising from the musical continuity
  4. Repetition
    Repetition (music)
    Repetition is important in music, where sounds or sequences are often repeated. One often stated idea is that repetition should be in balance with the initial statements and variations in a piece. It may be called restatement, such as the restatement of a theme...

     processes, in which movement is generated solely by extended repetition
  5. Electronic
    Electronic music
    Electronic music is music that employs electronic musical instruments and electronic music technology in its production. In general a distinction can be made between sound produced using electromechanical means and that produced using electronic technology. Examples of electromechanical sound...

     processes, in which some or all aspects of the music are determined by the use of electronics. These processes take many forms.

The first type is not necessarily confined to what are normally recognised as "chance" compositions, however. For example, in Karel Goeyvaerts’s Sonata for Two Pianos
Sonata for Two Pianos (Goeyvaerts)
Sonata for Two Pianos , also called simply Opus 1 or Nummer 1, is a chamber-music work by Belgian composer Karel Goeyvaerts, and a seminal work in the early history of European serialism.-History:...

, "registral process created a form that depended neither on conventional models nor … on the composer’s taste and judgment. Given a few simple rules, the music did not need to be 'composed' at all: the notes would be at play of themselves” (Griffiths 2011, 38).

Galen H. Brown acknowledges Nyman's five categories and proposes adding a sixth: mathematical process, which includes the manipulation of materials by means of permutation, addition, subtraction, multiplication, changes of rate, and so on (Brown 2010, 186).

Erik Christensen identifies six process categories (Christensen 2004, 97):
  1. Rule-determined transformation processes
  2. goal-directed transformation processes
  3. indeterminate transformation processes
  4. Rule-determined generative processes
  5. goal-directed, and generative processes
  6. indeterminate generative processes

He describes Reich's Piano Phase (1966) as rule-determined transformation process, Cage's Variations II
