How it's made
Source
a run of small glass bars or goblet rims flicked one after another, each excited by a 1–3 ms high-passed noise tick; the notes climb a scale so the run reads as a glissando.
Body
each glass rings in stretched, inharmonic modes (1 : 2.32 : 4.25 : 6.63); the upper modes die in 0.15–0.4 of the fundamental's decay, so the tick is bright and the tail is a nearly pure tone.
Shimmer
every note carries a second fundamental detuned by 3–7 Hz (two near-degenerate glass modes), which beats slowly; a faint octave-up partial slides in late so the tail sparkles instead of just fading.
Envelope
notes are spread over 0.3–0.9 s with later notes slightly stronger, then the pile of rings decays exponentially (0.5–1.4 s T60) and a short fade ends the one-shot at about 1.5 s.
Variation
`rng` jitters note timing (±8 % of a step), tuning (±0.15 %), strength and the detune of each pair; notes are panned left to right across the run so the gesture sweeps across the stereo field.
