Piano Discovery Stinger

How it's made

Source

felt hammers striking steel strings in the upper-middle register of a piano, played softly as a short rising phrase of 3-5 notes. Each strike is a 5-8 ms low-passed thump (felt) plus the string itself.

Body

every note is 8 partials at n * f0 * sqrt(1 + B n^2) (inharmonicity B = 0.0004, so the 8th partial sits about 1 % sharp). Each partial is a pair of strings 0.05-0.2 % apart, which makes the sustain shimmer slowly. Upper partials decay 2-6x faster than the fundamental: bright attack, warm pure tail.

Envelope

3 ms soft attack, then a double decay: a fast initial drop (prompt sound) into a long sustain tail of 1-3 s on the fundamental. The phrase holds back slightly before its last step, like a curious lift.

Variation

`rng` jitters note timing (+-3 %), and the tuning of every string; velocity rises through the phrase. Macros set the scale, tempo, note count, softness (hammer hardness and partial balance) and sustain.

Presets

curious (major pentatonic climb), wonder (lydian, slow, long sustain), twinkle (high, fast, light), mystery (minor, low, dark and soft).
