A♭ major chord

Home in A♭ major, and the V that pulls toward D♭.

How it sounds
Bright and settled. A♭ to C is four frets, and that gap gives it its warmth, while E♭ on top holds it steady. There’s no open grip. The lowest of its five grips is the G form, at the 1st fret.
Where it lives
The I of A♭ major, the IV of E♭ major and the V of D♭ major. In A♭ major it’s home; in D♭ major it pulls the song back to D♭. In C♯ harmonic minor it’s the V, and its third, B♯, is the raised seventh that leads back to C♯. In C♯ harmonic minor the same chord is written G♯. Gospel and soul, where pianists often play in A♭, and jazz. Guitarists usually meet it as a barre at the 4th fret.

Voicings across the neck

A♭, C and E♭ can be played in five places on the neck, each built from a different open chord shape. Neighbouring forms share a root, so each one hands over to the next, and together they run from the 1st to the 14th fret before the cycle starts again. The E form at the 4th fret is the fullest barre, all six strings. The D form at the 6th uses only the top four, which keeps it small and light.

R · M3 · P5: what each interval does in a chordA♭ · C · E♭4 + 3

A♭ major is a root, a major third and a perfect fifth: A♭, C and E♭, taken from the A♭ major scale by skipping every other note. Four then three is what makes a chord major. Turn the gaps round, three then four, and you get A♭ minor: A♭, C♭, E♭, the same chord as G♯m.

What each interval does

In these keys and scales

A♭ major turns up in twelve scales on the site, and the job it does depends on the scale. In A♭ major it’s the I, home. In D♭ major and C♯ harmonic minor (written G♯ there) it’s the V, the chord that pulls back home. In F minor it’s the III, the relative major inside the minor key, and as the VI of C minor it’s a warm step away from home. The numeral beside each scale names the job, and the name opens that scale’s page.

Progressions

A lot of progressions in A♭ major start on A♭, and nearly all of them come back to it. In I–⁠IV–⁠V the other two chords keep returning to it. In I–⁠V–⁠vi–⁠IV it opens the loop, and D♭ at the end leads back round to it. V–⁠I turns it the other way: there A♭ is the V, and it resolves to D♭.
