The rules

The construction rules C/B♭ follows

  1. Start from a triad

    Root, 3rd and 5th, stacked in thirds. The 3rd makes it major or minor; the 5th makes it diminished or augmented when it moves.

  2. A slash names the bass

    Chord/bass puts any note under a triad. A chord tone gives an inversion, such as C/E; another note gives a new chord: G/F is G7 with the 7th in the bass.

All the rules, with examples, in the guide to the chord library.
