About the B flat six over nine chord
The B flat six over nine chord is a B flat six-nine built from B flat, D, F, G, C. It sits outside the plain diatonic set, so it is borrowed to add color and tension. Tap the keys or frets above to hear each note, or press Play chord to hear them together.
It is also written A sharp six over nine , which spells the same notes enharmonically.

Functional relationships
These chords are where this one most naturally comes from and resolves to inside a key.
The relative minor uses the same notes and key signature, so it works as a calmer, darker home base.
The parallel minor keeps the same root note but lowers the third, giving the same key a darker, sadder sound.
The dominant is a fifth above the root, and it builds tension that pulls strongly back to this chord.
The subdominant is a fourth above the root (a fifth below), and it usually leads on to the dominant or back home.
The tritone substitution stands in for this chord's dominant with a dominant seventh a half step above the root, which slides down by a half step to resolve here.
What do the colors mean?
