// GOOD LUCK! (You're gonna need it) A piano duet. My addition to the impossible piano epics here on musescore! (also the first song I have ever written!) — Josiah Von Duhlstine
// 126 bpm, 4/4, key Eb major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: Tempo changes preserved in elapsed time; displayed bars use the dominant tempo.
// note: Transcription provider: pdmx. https://musescore.com/score/927001; license: https://creativecommons.org/publicdomain/mark/1.0/
// note: Full arrangement: all 69 bars on a 32-step grid, each part at one level. Source detail keeps the original performance.
setcpm(126/4)

// 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.
