The rules

The construction rules B♭sus4 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. Sus chords replace the 3rd

    A 2nd or a 4th takes the 3rd’s place, so the chord is neither major nor minor and wants to resolve. 7sus4 keeps the ♭7 for a dominant without its 3rd.

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