// Le Temps passe — Brassens Georges
// 250 bpm, 2/2, 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 (2/2 at bar 1, 3/4 at bar 35, 2/2 at bar 54, 3/4 at bar 88, ...) are rendered on a constant 2/2 grid of one bar per cycle
// note: Full arrangement: all 164 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
setcpm(250/4)

// 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.

// chords · electric guitar jazz
