// The sound of the house: koto for readiness, the wind chime for people
// arriving and leaving, the shoji door for a new video, bamboo for chat,
// clappers for a kick, the singing bowl for the idle warning, a string
// going slack and re-tuned for the connection. All in the Yo scale on D
// (D E G A B), so overlapping sounds agree; quiet and short.
// The app's sounds come in presets; each action can take its sound from any
// of them. Every preset is quiet, short and on D, so sounds from different
// presets still agree when they overlap.
// - Cosmic: star bells, stardust, bubbles, soft pads, a space tail.
// - Abyss: deep space and its dread. Far beacons, nebula washes, slow
// beating clusters and tritone sags, on D phrygian, with a vast tail.
// - Wood & glass: plucked strings, glass bells, wood knocks, a short room.
