A written notation of a musical or dance composition, which allows the work to be performed at a later date or by another performer. Composers interested in incorporating non-traditional sounds into their music and choreographers experimenting with different kinds of movement invented new notational symbols for their scores, which could be read by non-specialists or artists from other disciplines. Scores are as varied as the artists who make them and can feature, for example, magazine and newspaper clippings, drawings, or color-coded stage directions.
