Music in A-flat minor

Although A-flat minor occurs in modulation in works in other keys, it is only rarely used as the principal key of a piece of music. Some well-known uses of the key in classical and romantic music include:

More often, pieces in a minor mode that have A-flat's pitch as tonic are notated in the

enharmonic key, G-sharp minor
, because that key has just five sharps as opposed to the seven flats of A-flat minor.

In some scores, the A-flat minor key signature in the bass clef is written with the flat for the F on the second line from the top.[nb 1]

Notes
