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.

To play C♯6 on piano, place your right hand with your thumb on C♯, index finger on E♯, middle finger on G♯ and little finger on A♯. Press the keys together and listen for an even sound. On the keyboard C♯, G♯ and A♯ are black keys and E♯ is white, the key you'd normally call F. The thumb starts on a black key, so slide the whole hand a little further in, towards the fallboard. Practice moving in and out of the chord slowly, then bring in a metronome.

How to use the C♯6 chord

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

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