The work is not to be conducted, as in most late Cage-compositions. Each player has his own
chronometer and he/she decides on the starting time, sometime during or after the tuning of the instruments. The composition
uses timebrackets, most of them flexible. Each part has some of the timebrackets deleted, resulting in a changing
of ensemble composition throughout the work.
