Secret Revealed

How it's made

Source

a celesta or glass-harp style keyboard played as a fast rising arpeggio that lands on a chord. Each note is a soft mallet strike: a 3 ms ramp with a faint high-passed noise tick, no hard transient.

Body

every note is a fundamental plus bell-like partials (2.01x, 3.02x, 4.1x). The upper partials decay faster than the fundamental, so each strike glints and settles. A second fundamental detuned by a few cents beats slowly against the first and gives the shimmer.

Harmony

five rising notes climb through an unstable interval pattern (diminished steps, tritone or whole-tone) and stop on a leading tone; a major chord (root, third, fifth an octave up) then resolves it. The mystery is the unresolved climb, the brightness is the resolution and its longer ring.

Envelope

arpeggio notes ring 0.3 s and overlap; the chord rings for `ring` seconds, strummed over 40 ms. The whole gesture is about 1.5 s and ends with a smooth fade.

Variation

`rng` detunes each note by +-0.2 % and each partial by +-0.15 %, and varies the tick; notes pan in a rising sweep from left to right. Presets change the interval pattern, tempo, brightness and ring.
