// 120 bpm, 4/4, key A major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: ch 14 "Double Bass" named as a bass, played on acoustic bass (its contrabass patch is not one)
// note: Transcription provider: pdmx. https://musescore.com/score/4177661; license: https://creativecommons.org/publicdomain/mark/1.0/

// Notation: c3@3 lasts 3 steps · ~ is a rest · [c3,e3] is a chord · [...]/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.
