The MOCAK Collection contains several dozen scores of experimental music. These are usually musical notations written in private languages and intended for performers who work directly with the composer. The starting point for this part of the exhibition are works shown in the Polish Institutes in Prague (1983) and Paris (1985), and at the Royal Academy of Music in London (1986) during the exhibition Musical Score as Piece of Art. These include graphic scores by Marek Chołoniewski, Piotr Grella-Możejko, Krzysztof Penderecki, Bogusław Schaeffer and Ewa Synowiec. Some of the artists were associated with the Polish Radio Experimental Studio, established in 1957 in Warsaw. The exhibition also includes archival material and recordings.
Another part of the exhibition consists of scores understood in a broader sense. These are written down and drawn plans of action and performance, several of which took place in Krakow. Their creators originated primarily from Fluxus, one of the most famous artistic groups in the world. Many of its members took part in 1958 in a course in experimental music led by John Cage at The New School, New York.
At the exhibition museum is showing documentation of the work of Dick Higgins, Al Hansen and Milan Knížák. With the permission of the latter, MOCAK has made a remake of his work Destroyed Music, which includes gramophone records that are scratched, have been cut up or painted over.
