A-flat major (or the key of A-flat) is a major scale based on A♭, with the pitches A♭, B♭, C, D♭, E♭, F, and G. Its key signature has four flats.

The A-flat major scale is:

${ \omit Score.TimeSignature \relative c'' { \key aes \major \time 7/4 aes bes c des es f g aes g f es des c bes aes \clef F \key aes \major } }$

Its relative minor is F minor. Its parallel minor, A-flat minor, is usually written instead as the enharmonic key of G-sharp minor, since A-flat minor, which contains seven flats, is not normally used. Its enharmonic, G-sharp major, with eight sharps, including the F, has a similar problem, and so A-flat major is often used as the parallel major for G-sharp minor. (The same enharmonic situation also occurs with the keys of D-flat major and C-sharp minor.)
