Breath Aeolian
Breathe into a living cloud of air and hear the air sing back — your breath injects wind into a fluid, and the vortices it stirs make aeolian tones whose pitch is set by airflow physics, not by any scale.
Pale luminous vapor on deep charcoal. Seven reeds stand in the rising column. Wind shedding past each one whistles at f = St·U/d.
Allow the microphone to breathe into it directly. If you decline, a synthetic breath keeps the cloud alive and singing.
