// Frog-I-More Rag — Morton Jelly Roll
// 192 bpm, 4/4, key C major. Source: midi.
// Generated by strudelify. One cycle = one bar.

// 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.
