Short answer

Major sixth chords sound bright and settled without the pull of a seventh. Adding a major sixth to a major triad gives a warm, slightly retro colour that filled swing bands and fifties pop, and it still ends a song beautifully.

How to use the A♭6 chord

The A♭6 chord is built from a root, a major third, a perfect fifth and a major sixth. Start at the root A♭ and stack the intervals to get the whole chord: A♭, C, E♭ and F. The same formula gives you the chord in any other key.

Major sixth chords work as a softer substitute for a major triad, especially as a final chord where a maj7 would sound too jazzy. Swing, rockabilly, bossa nova and country all lean on them.

How A♭6 differs from similar chords

A♭6 and A♭maj7 both add one note to A♭, but the sixth sits a whole step below the major seventh and makes no dissonance with the root. A♭6 has exactly the same notes as the minor seventh chord a minor third below it, so the bass note decides which of the two you hear.

Where A♭6 is used

A major chord is at home as a tonic, and just as useful as the IV or the V of a neighbouring key. Each progression below is written in the key its numerals name.

As the tonic (I)A♭ major
  1. I6A♭6
  2. vi7Fm7
  3. ii7B♭m7
  4. V7E♭7

Home. The loop leaves A♭6 and keeps coming back to it.

As the goal of a ii-V-IA♭ major
  1. ii7B♭m7
  2. V7E♭7
  3. I6A♭6

The oldest cadence there is: two chords of preparation, then A♭6.
