B♯6/9 Chord: Guitar, Piano and Notes
The B♯6/9 chord is a six-nine chord built on the root note B♯. Its notes are B♯, D𝄪, F𝄪, G𝄪 and C𝄪. It's enharmonically the same chord as C6/9.
Six-nine chords sound bright and pleasantly unresolved. A major sixth and a ninth sit on the triad with no seventh at all, so the chord never pulls toward a resolution and can simply sit there, which is why bands often end a song on one.

How to use the B♯6/9 chord
The B♯6/9 chord is built from a root, a major third, a perfect fifth, a major sixth and a major ninth. Start at the root B♯ and stack the intervals to get the whole chord: B♯, D𝄪, F𝄪, G𝄪 and C𝄪. The same formula gives you the chord in any other key.
Six-nine chords are a favourite ending for jazz standards and pop ballads, taking the place of a plain major or major seventh chord as the final I. They also work as a colourful substitute for a major triad anywhere in a progression.
How B♯6/9 differs from similar chords
B♯6/9 adds both the sixth and the ninth to B♯ and leaves out the seventh, which separates it from B♯maj9 and B♯13. With no seventh and no fourth, none of its notes clash, so nothing in it needs to resolve. Its five notes are the major pentatonic scale stacked into one chord.
