B♯m6 Chord: Guitar, Piano and Notes
The B♯m6 chord is a minor sixth chord built on the root note B♯. Its notes are B♯, D♯, F𝄪 and G𝄪. It's enharmonically the same chord as Cm6.
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 B♯m6 chord
The B♯m6 chord is built from a root, a minor third, a perfect fifth and a major sixth. Start at the root B♯ and stack the intervals to get the whole chord: B♯, D♯, F𝄪 and G𝄪. 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 B♯m6 differs from similar chords
B♯m6 adds a major sixth to B♯m, where B♯m7 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.
