152 Reason and Record song files, 76 for each program, or 76 for v6 and up.

1 Music Theory overview  - a song file that works as a course covering everything from sight reading to time signatures, the circle of fifths, chord construction and more.

17 Chord files containing 82 chords, each in individual clips organized four different ways: by quality, type, interval structure, and type versus structure.
