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 G♭6 chord

The G♭6 chord is built from a root, a major third, a perfect fifth and a major sixth. Start at the root G♭ and stack the intervals to get the whole chord: G♭, B♭, D♭ and E♭. 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 G♭6 differs from similar chords

G♭6 and G♭maj7 both add one note to G♭, but the sixth sits a whole step below the major seventh and makes no dissonance with the root. G♭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 G♭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.
