Piano Works Steffen Schleiermacher

In the last years of his life, John Cage wrote a great many so-called 'Number Pieces' – the title indicating the number of performing musicians. While most of these pieces indicate which instruments are to be played, as well as the sounds that are to be produced, other pieces offer only general tone descriptions or a framework for choosing the tones oneself. What these pieces do have in common is time-organization: Cage designates the measure within which the tones must be played.
