Short answer

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.

Where B♭6/9 is used

A major chord is at home as a tonic, and just as useful as the IV or the V of a neighbouring key. Each progression below is written in the key its numerals name.
