B♯6 Chord: Guitar, Piano and Notes
The B♯6 chord is a major sixth chord built on the root note B♯. Its notes are B♯, D𝄪, F𝄪 and G𝄪. It's enharmonically the same chord as C6.
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.

How to use the B♯6 chord
The B♯6 chord is built from a root, a major 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.
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 B♯6 differs from similar chords
B♯6 and B♯maj7 both add one note to B♯, but the sixth sits a whole step below the major seventh and makes no dissonance with the root. B♯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.
