// Don Giovanni K.527 — Wolfgang Amadeus Mozart
// 54 bpm, 2/4, key A major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: Tempo changes preserved in elapsed time; displayed bars use the dominant tempo.
// note: metre changes (2/4 at bar 1, 6/8 at bar 49) are rendered on a constant 2/4 grid of one bar per cycle
// note: ch 2 "Bass" named as a bass, played on electric bass finger (its choir aahs patch is not one)
// note: Transcription provider: pdmx. https://musescore.com/score/586456; license: https://creativecommons.org/publicdomain/mark/1.0/
// note: Full arrangement: all 74 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.

// Notation: c3@3 lasts 3 steps · ~ is a rest · [c3,e3] is a chord · "a, b" plays two voices at once · [...]/2 spreads a riff over 2 bars.
// A part's distinct bars are riffs (A, B, C...) played in order: edit a riff to change every repeat.
