Strings played by the wind. Each string sheds vortices at a rate set by wind speed and its thickness, and sings whichever of its harmonics is nearest. Several strings of different thickness, tuned to one note, sing different harmonics at once; gusts move them around. Louder = more wind = higher harmonics.
Two long notes with four strings and slow gusts: listen to the harmonics swap on their own.
Rough, breathy whistling in gusty wind.
The swell phrase: harmonics climb as the wind rises within each note.
One thick string in a light breeze: a pure hovering tone.
Bowed glass whose overtones melt toward a harmonic tone as the bow presses harder, and drift on their own. "Melt" is a slow phrase with swells inside each note, so you can hear the glass change under the bow.
Glass harmonica that melts into a pure, harmonic tone the harder you press.
Singing bowl: paired modes beat slowly; pressing hard merges the pairs.
Impossible bar: highs outlast the fundamental, modes drift between tunings.
Hard, bright tuned bar with a grabby bow; barely melts.
Arpeggio C3 to C6 and back.
Twinkle Twinkle (soft start, swell, loud return, fade) in each preset, plus a few register tests.
Dark, breathy, slow vibrato, slides between notes, long hall.
Plain woody clarinet in a small room.
Bright and buzzy (small reed opening), fast shimmer, long bright tail.
Very dark and soft, almost flute-like.
Mostly air: heavy turbulence on a fragile tone.
Bass-clarinet register.
Arpeggio C3 to C6 and back.
