// Song of Durin for Tuba Quartet — Clamavi de Profundis
// 90 bpm, 4/4, key Db 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 (4/4 at bar 1, 6/8 at bar 42, 6/4 at bar 71, 4/4 at bar 73) are rendered on a constant 4/4 grid of one bar per cycle
// note: Transcription provider: pdmx. https://musescore.com/score/5634108; license: https://creativecommons.org/publicdomain/zero/1.0/
// note: Full arrangement: all 110 bars on a 32-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.
setcpm(90/4)

// Notation: c3@3 lasts 3 steps · ~ is a rest · [...]/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.
