Graphic notation (or graphic score) is the representation of music through the use of visual symbols outside the realm of traditional music notation. Graphic notation evolved in the 1950s, and can be used either in combination with or instead of traditional music notation. . Composers often rely on graphic notation in experimental music, where standard musical notation can be ineffective. Other uses include pieces where an aleatoric or undetermined effect is desired. One of the earliest pioneers of the technique, along with John Cage, was Earle Brown, who sought to liberate performers from the constraints of notation and makes them active participants in the creation of the music.

History
Graphic notation first appeared in the 1950s as an evolution of movement of Indeterminacy as pioneered by John Cage. The technique was originally used avant-garde music and manifested itself as the use of symbols to convey information that could not be rendered with traditional notation such as extended techniques. Graphic scores have, since their conception, evolved into two broadly defined categories, one being the invention of new notation systems used to convey specific musical techniques and the other the use conceptual notation such as shapes, drawings and other artistic techniques that are meant to evoke improvisation from the performer. Examples of the former include Feldman's Projection and Stockhausen's Prozession. Examples of the latter include Earle Brown's December 1952 and Cardew's Treatise, which was written in response to Cage's 4'33" and which he wrote after having worked as Stockhausen's assistant. The score comprises of 193 of lines and rectangles on a white background where. Here the lines represented elements in space and the score was merely a representation of that space at a given instant. In Europe, one of the most notable users was Sylvano Bussotti, whose score were even often displayed as pieces visual art by enthusiasts. In 1969, in an effort to promote the movement of abstract notation, John Cage and Allison Knowles published an archive of excerpts of scores by 269 composers with the intention of showing "the many directions in which notation is now going".

Other notable pioneers of graphic notation include composers such as Roman Haubenstock-Ramati, Mauricio Kagel, György Ligeti (Artikulation), Krzysztof Penderecki, Karlheinz Stockhausen, and Iannis Xenakis, Morton Feldman, and Christian Wolff.

In 2008, Theresa Sauer edited a compendium featuring graphic scores by composers from over fifty countries, demonstrating how widespread the practice has become.

As a Notational System

 * Time based pictographic scores such as "Waterwalk" by John Cage, uses a combination of time marking an pictographic notation as instruction on how and when to perform certain actions.


 * Line staves showing approximate pitch, with the actual pitches being decided upon performance.


 * Altered Notation can be seen in George Crumb's work where he uses traditional notation but presents the music on the page in a graphic or nontraditional manner such as spirals or circles.


 * New Specific Notation System, that is, a new of specifically and graphically notate musical actions like that of Xenakis' Psappha.

As Abstract Visual Reference

 *  Time Based Abstract Representation, can be seen in Hans-Christoph Steiner's score for Solitude in which the music is represented using symbols and illustrations. Note that here, time is still represented horizontally from left to right like in a pitch graph system, and thus implies that the piece as a specific form.[[Image:solitude.png|thumb|600px|center|Hans-Christoph Steiner's score for Solitude, created using [[Pure Data]]'s data structures.]]


 * Time Based Abstract Notation, such Rudolf Komorous's "Chanson" utilises abstract notation with time indication, or least a direction in which the piece is read and therefore implies a form.


 * Free Abstract Representations, such as Brown's December 1952, where the form, pitch material and instrumentation are left up to the performer.


 * Free Abstract Notation, such as Mark Applebaum's "The Metaphysics of Notation" and where elements of traditional music notation are melded with abstract designs.
