A sequential curriculum organized as a progressive map, split into Rhythm and Pitch tracks. Content unlocks as you demonstrate competence, so the path is always at the edge of what you can currently do.
You don't start at the beginning; you start where you actually are. The map reveals content as you demonstrate competence, one node at a time, so nothing is locked behind time spent, only skill shown.
Meter, rhythmic reading and reproduction, subdivision, rhythmic dictation, polyrhythms, and more; the full track goes beyond what is listed here.
Intervals, chord qualities, chord progressions, melodic dictation, and more, built up in the same competence-gated steps; these descriptions are not exhaustive.
Campaign supplements existing theory and musicianship sequences rather than replacing them. If you have a teacher, it is what you do between lessons. If you don't, it is a foundation you can build without one.
