Source: a small electronic sounder driven by a triangle wave, played as two mid-register notes. A second, slightly detuned triangle (about 4 cents) thickens the note, and a quiet sine one octave below gives body.
Body: the triangle's odd harmonics are shaped by a low-pass that sits a few times above the fundamental, so the tone is soft but clearly pitched; a faint breath of band-passed noise at the onset keeps the attack natural without a click.
Envelope: each note has a 10 ms attack, a flat sustain (steady level, no decay) and a 35 ms release; the two notes are separated by a short gap. The pair forms an open interval that does not land on a chord tone, so the phrase feels unresolved.
Variation: pitch, the interval between the notes, note length and brightness; `rng` offsets the detune by a few thousandths so renders are never perfectly sterile.
