// Venus callipyge — Brassens Georges
// 200 bpm, 6/8, key F major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: metre changes (12/8 at bar 1, 6/8 at bar 17, 12/8 at bar 117, 6/8 at bar 133, ...) are rendered on a constant 6/8 grid of one bar per cycle
// note: Full arrangement: all 188 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
setcpm(200/3)

// 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.
