Triple Music
Around 1948 Cage wrote an article named A Composer's Confessions.
In the last part of this text he mentiones looking forward to working with Lou Harrison and Merton Brown. The work to be
composed, should have been written, combining the techniques of their chromatic counterpoint with Cage's structural
rhythm, thus providing a means where 3 or 4 people might collaborate on 1 piece of music. The piece was never
composed, though.
