Why it sounds like that

A♭ major is built from the formula 1, 3, 5, with the major third C giving it its bright quality. Compare it to A♭ minor, which lowers the third to C♭.

What goes wrong with A♭ major?

  • Not pressing the barre hard enough, causing the high e to buzz.
  • Letting the middle finger touch the D string and deaden it.

When to use it

A♭ major is the tonic in A♭ major, so it anchors progressions like A♭–D♭–E♭, the I–IV–V. It also appears in C♯ major and E♭ major keys. Use it for jazz, pop, and rock.

Changing to and from A♭ major

  • Sliding the shape down two frets to the 2nd fret gives F♯ major.
  • From A♭ major to E♭ major, move the barre to the 6th fret and adjust the other fingers to the E♭ shape.

Which voicing to use

The 4th fret barre shape is the standard, but the A♭/C inversion with C in the bass offers a different sound. The 11th fret barre shape gives a higher voicing.

Common questions

How is A♭ major written?

A♭ major is written as A♭, A♭maj, or A♭M. On a keyboard, use the ASCII root Ab. It is also spelled G♯ in enharmonic notation for the same sounding root.

What is the difference between A♭ major and A♭ minor?

A♭ major has a major third (C), while A♭ minor has a minor third (C♭). This changes the chord from bright to somber.
