A6 Chord

The A6 chord is a major sixth chord built on the root note A. Its notes are A, C♯, E and F♯.

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 A6 chord

The A6 chord is built from a root, a major third, a perfect fifth and a major sixth. Starting from the root A, stack the intervals to get the complete chord: A, C♯, E and F♯. Learning the formula is the fastest way to transpose the chord to 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.
