Quality
Short answer

Minor sixth chords are darker than a plain minor triad but never sour. A major sixth sitting over a minor third gives them a wistful, cinematic quality that turns up in bossa nova, French chanson and film noir scores.

How to use the Cm6 chord

The Cm6 chord is built from a root, a minor 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.

Minor sixth chords act as the iv chord in a major key or as the tonic of a Dorian passage, and they are a staple of jazz turnarounds. They also make a striking substitute for a plain minor chord at a cadence.

How Cm6 differs from similar chords

Cm6 adds a major sixth to Cm, where Cm7 adds a minor seventh a half step higher. That major sixth forms a tritone with the minor third, which gives the chord its bittersweet tension. The same four notes spell the half-diminished chord built on its sixth.

Where Cm6 is used

A minor chord works as the tonic of its own key, and as the vi or the ii of a major one. Each progression below is written in the key its numerals name.
