How it's made
- Source
- the plunger of a desk bell is pressed once; a spring-loaded hammer taps the inside of a small steel dome. The tap is a 0.5–3 ms broadband click (hard metal on metal) plus a short, dull thunk (60–120 Hz body of the base and plunger housing) lasting about 25 ms.
- Body
- a shallow dome rings in few inharmonic modes, relative to the main mode: 1, 2.32, 3.86 and 5.6. Each is a pair of modes a fraction of a hertz apart (the dome is not perfectly round), so the tail shimmers slowly. Decay times fall with frequency: the main mode rings about 1.3 s, the top mode under 0.25 s.
- Envelope
- the strike is instant; upper modes die first so the attack is bright and the tail a clean, pure high tone. A short fade-out after the ring ends keeps the tail free of clicks.
- Variation
- `rng` mistunes the modes by ±0.3 % and varies the tap click; `pitch` scales every mode (dome size), `decay` the damping, `brightness` the upper modes, `strike` the hardness of the tap.
