Air is a work for fixed media and optional live improvisation by a solo instrumentalist with a duration of 60 minutes. The piece is for a 60-minute yoga practice. Here is the score. It basically shows the timings and durations of events, meter, pitches and cues. It is a map for both the soloist and yogi.

A playing of Air without a soloist is absolutely acceptable.
