How it's made
Source
a steel tine of a thumb piano (kalimba) plucked by a thumbnail, played as two notes in quick succession.
Body
a clamped-free bar, so the partials are strongly inharmonic: fundamental 1, a bright "ping" at about 6.3×, and a faint one at about 17×; a soft octave (2×) adds the warm wooden-box sustain. The fundamental rings longest, the upper partials die within a fraction of it, so the attack is metallic and the tail is pure and warm.
Buzz
a loose ring or bridge rattle makes a short band-limited noise burst, amplitude-modulated at the note's pitch, that fades faster than the tone (`buzz`).
Envelope
a 1.5 ms thumbnail strike (a tiny high-passed click), then an exponential decay of 0.25–0.9 s; the second note starts `spacing` seconds later and rings over the first.
Variation
`rng` detunes each partial by a fraction of a percent; `interval`, `pitch`, `brightness` and `buzz` shape the character.
