// Te Deum (Prelude) — Marc-Antoine Charpentier
// 120 bpm, 2/2, key C major. Source: midi.
// Generated by strudelify. One cycle = one bar.
// note: metre changes (1/4 at bar 1, 2/2 at bar 2, 1/4 at bar 10, 2/2 at bar 10) are rendered on a constant 2/2 grid of one bar per cycle
// note: ch 1 "C Trumpet" named as a brass, played on trumpet (its acoustic bass patch is not one); ch 16 "Double Bass" named as a bass, played on acoustic bass (its contrabass patch is not one)
// note: duplicate parts dropped: ch 4 "Violins 1" string ensemble 1 (copy of ch 1 "C Trumpet" trumpet); ch 7 "Flute" flute (copy of ch 1 "C Trumpet" trumpet); ch 8 "Oboe" oboe (copy of ch 1 "C Trumpet" trumpet)
