This is an excerpt from an arbitrarily-long generative piece composed for an upcoming production of Samuel Beckett's "Play". Written in Csound, made out of sine waves (three groups of three).
Update: There is a very nice write-up on this piece by Marc Weidenbaum at http://disquiet.com/2015/05/17/sine-waves-for-samuel-beckett/.
