C#m6 Chord (Minor 6th)

The minor 6th chord adds a natural 6th to a minor triad — root, flat 3rd, 5th, natural 6th — a distinctly different colour from min7. The notes of C#m6 are C#, E, G#, A#.

Noir and jazz-minor territory: it’s the chord under a moody vamp that wants darkness without the softness min7 would add.
