// Gastibelza — Brassens Georges
// 120 bpm, 6/8, key A major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: duplicate parts dropped: ch 2 "Chitarra" electric guitar jazz (copy of ch 1 "Melodie" muted trumpet)
// note: Full arrangement: all 141 bars on a 16-step grid, each part at one level. Source detail keeps the original performance.
setcpm(120/3)

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

// chords · electric bass pick · "Basso"
