Experimental music is a term introduced by composer John Cage in 1955 and defined as 'an act the outcome of which is unknown".

In a broader sense, it has come to mean any music that challenges the commonly accepted notions of what music is. There is an overlap with avant-garde music. David Cope describes experimental music as that, "which represents a refusal to accept the status quo" (Cope, 1997, p. 222)

Michael Nyman (1974) uses the term "experimental" to describe the work of American modernist composers (John Cage, Christian Wolff, Earle Brown, Meredith Monk, Malcolm Goldstein, Morton Feldman, Terry Riley, La Monte Young, Philip Glass, Steve Reich, etc.) as opposed to the European avant-garde at the time (Karlheinz Stockhausen, Pierre Boulez, Iannis Xenakis). The "experiment" in this case is not whether a piece succeeds or fails, but is in the fact that the outcome of the piece is uncertain or unforeseeable (Cage 1961, 13).

According to David Nicholls, "...very generally, avant-garde music can be viewed as occupying an extreme position within the tradition, while experimental music lies outside it" (Nicholls 1998, 318). That tradition is the inheritance of common-practice Western art music, with its concern for increased technical complexity, historical inheritance, composer intention and other features. In general, and at least originally, experimental music took its inspiration from non-Western sources and from varying times. It may take its inspiration (directly in terms of generating systems) from other media; practitioners may or may not be professionals in the traditional sense of the word, although they may still be trained in their work and adept at it.

As with other edge forms that push the limits of a particular form of expression, there is little agreement as to the boundaries of experimental music, even amongst its practitioners. On the one hand, some experimental music is an extension of traditional music, adding unconventional instruments, modifications to instruments, noises, and other novelties to (for example) orchestral compositions. At the other extreme, there are performances that most listeners would not characterize as music at all.

While much discussion of experimental music centers on definitional issues and its validity as a musical form, the most frequently performed experimental music is entertaining and, at its best, can lead the listener to question core assumptions about the nature of music.

The term "experimental music" was used contemporaneously for electronic music, particularly in the early musique concrète work of Schaeffer and Henry in France and in the Experimental Studios at the University of Illinois, run by Lejaren Hiller. "Experimental" electronic composition may be "experimental" in the sense used in Nyman (for instance, Cage, Cartridge Music or the early work of Alvin Lucier); it may also lie more comfortably with the avant garde.

Keywords

Indeterminacy in music - (Indeterminate music) Related to 'chance music' (one of Cage's terms). Music in which the composer introduces the elements of chance or unpredictability with regard to either the composition or its performance. This term is used by experimental composers, performers and scholars working in experimental music in the United States, Britain, and in other countries influenced by Cagean aesthetics.

Aleatoric music - A term coined by Werner Meyer-Eppler and used by Boulez and other composers of the avant garde (in Europe) to refer to a strictly limited form of indeterminacy, also called "controlled chance". As this distinction was misunderstood, the term is often (and somewhat inaccurately) used interchangeably with, or in place of, "indeterminacy".

Graphic notation - Music which is written in the form of diagrams or drawings rather than using “conventional” notation (with staves, clefs, notes, etc).

Literalism - Music that rejects the aesthetic as motivating force for the creation and pursuit of sound, using either the basic building blocks of orchestral composition (strict literalism) or sounds present at the site of performance (direct literalism) instead.

Microtones - A pitch interval that is smaller than a semitone. This includes quarter tones and intervals even smaller. Composers have, for example, divided the octave into 22, 31, 43, 53, 72, etc. microtones, either equally or unequally, and then used this scale as a basis for composition.

Techniques

Some of the more common techniques include:

• Extended techniques: Any of a number of methods of performing on a musical instrument that are unique, innovative, and sometimes regarded as improper.

• "Prepared" instruments—ordinary instruments modified in their tuning or sound-producing characteristics. For example, guitar strings can have a weight attached at a certain point, changing their harmonic characteristics (Keith Rowe is one musician to have experimented with such techniques). Cage's prepared piano was one of the first such instruments.
• Unconventional playing techniques—for example, strings on a piano can be manipulated directly instead of being played the orthodox, keyboard-based way (an innovation of Henry Cowell's known as "string piano"), a dozen or more piano keys may be depressed simultaneously with the forearm to produce a tone cluster (another technique popularized by Cowell), or the tuning pegs on a guitar can be rotated while a note sounds (called a "tuner glissando").

• Incorporation of instruments, tunings, rhythms or scales from non-Western musical traditions.
• Use of sound sources other than conventional musical instruments such as trash cans, telephone ringers, and doors slamming.
• Playing with deliberate disregard for the ordinary musical controls (pitch, duration, volume).
• Use of 'radical' scores which serve as non-conventional written/graphic 'instructions' to be actively interpreted by the performer(s). Cage is credited with the original development of the radical score and this influence continued through other composers/artists such as La Monte Young, George Brecht, Yoko Ono, and far beyond.
• Creating Custom-made instruments for enhancing the timbre of compositions and exploring new techniques or possibilities.
