In full light, the performer begins playing a constellation (complex chord), pulsing individual notes of the chord over the whole range of the instrument, moving arms, hands, and body. The pulses should not be evenly spaced, but the chord should remain constant.
A bright strobe light begins to pulse slowly, at the rate of a heatbeat, focused on the performer. House lights are slowly dimmed. The player continues playing notes in strobe light only.
Strobe and performer continue with same pace of motion, but striking notes less and less. The sounds become gradually thinner (more widely spaced in time) but the performer's motions continue as before, as if playing the same number of notes but missing some. (Some of the notes become silent.) The result should be sounds and pulses of light that are no longer necessarily coordinated.
The performer becomes silent, continuing motion without any sound in the slow strobe light. A series of still "shots" of the performer in different positions is created.
The strobe slows down more and more, until just darkness. Strobe off.
A constellation of regular sound pulses emerges gradually (in volume) in darkness via an offstage piano or a recording of the instrument. The performer exits invisibly and silently in darkness. Only sounds here.
Spot light is raised on the space where the performer was while the tones continue to pulsate.
End by cutting spotlight and sound simultaneously.
