A Breath Flute
Fingering alone is silent. Hold a hole, then blow into your microphone — or hold Space. Blow harder and the tone brightens, not just loudens: the air, the overtones and the membrane's colour are all synthesized live in the page, never replayed. No microphone? Press "Hear it".
Turn on the microphone to blow with your breath, or just hold Space.
