cytophone

Three resonant colonies — small fields of ringing bodies you seed, strike, and let collide. Each is the same instrument read by a different physics. Two of them strike; one holds. Run together, they fall into register and become one body of water.

understory
low · struck · 58–360 hz
Circular-membrane gongs on a real drumhead spectrum — bronze, inharmonic, long-decaying. The floor.
halocline
mid · bowed · 140–520 hz
A boundary layer that sings. Bodies swell into held tones that breathe on a slow current and beat against themselves. The bed.
xenolith
high · struck · 78–1020 hz
Decoupled modal synthesis — bell-glass, clangorous, oil-slick. Impossible materials by geometry × substance. The sparkle.
