The notes in C6
A major sixth chord is spelled from its root up: C (R), E (3), G (5), A (6). Those are the only notes in C6 — play them in any order, in any octave, and it's still C6.
What a major sixth chord is
In plain terms, a major 6th adds the sixth to a major chord (root, 3rd, 5th, 6th) — a sweeter, more vintage alternative to the major 7.
How it's used: A soft, finished-sounding tonic: many old standards end on a 6 chord instead of a plain major for a warmer button.
The sound: Warm, nostalgic, breezy — 'sunny vintage'. Where you'll hear it: Jazz standards, swing, surf, and final chords that want to smile.
Hear C6 in a progression
A warm I6–IV vamp — that added 6th is the vintage sweetness. Press play, and drag the Key control to move it anywhere.
