Key Signature
A chord has no key signature of its own, but the A♭ Minor is the tonic (i) chord of A♭ Minor, which shares the signature of its relative major, C♭ Major: 7 flats (B♭, E♭, A♭, D♭, G♭, C♭, F♭).
Order of flats
Flats are added in a fixed order — the reverse of the sharp order. Each new flat key adds the next flat on the list.

Where these facts come from
Every value on this page is derived from the note formula for a minor applied to the root A♭, using standard music theory. Nothing here is hand-entered per chord, so the notes, intervals, inversions and frequencies cannot drift out of agreement with each other. Pitches assume 12-TET at A440.
