Treatise Animated for learning here:
'Treatise' once described as the Mount Everest of graphic scores was written from 1963 - 1967 and consists of 193 pages of numbers, shapes and symbols (some musical) whose interpretation is left up to the performer.
While the composer Cornelius Cardew has never given explicit instructions on how it should be performed, he has suggested that performers devise rules for themselves in advance. This (animated) presentation outlines consistent features of the piece and suggests possible interpretations. You are invited to perform your own analysis as well..
