Bbm9 Piano Chord

How to play Bbm9 on piano, step by step

1. Start on the B♭ below middle C. That is the lowest note of the chord.
2. Thumb (1): B♭
3. Index finger (2): D♭
4. Middle finger (3): F
5. Ring finger (4): A♭
6. Little finger (5): C
7. That reach is wider than an octave, so most players split it: play B♭ with the left hand and the other notes with the right. If you keep it in one hand, leave out the fifth (F), the note the chord misses least.

The top four notes, D flat, F, A flat and C, are exactly Dbmaj7. Hold B flat in the left hand, play that shape with the right, and the whole chord is there with no stretch.

If it sounds wrong

The hand slides off the black keys

Three of the five notes are black. Play close to the fallboard so the thumb and middle finger reach B flat and F without the hand tipping.

The reach is too wide

B flat to C is a ninth. Split the chord, or leave out the F and play B flat, D flat, A flat and C: still fully Bbm9.

It sounds like a major chord

Without the root the top four notes are Dbmaj7. The left hand B flat is what makes it minor, so make sure it actually sounds.

What makes it a Bbm9

B♭ · D♭ · F · A♭ · C | 1 ♭3 5 ♭7 9

Bbm9 is Bbm7 with a ninth added: B flat, D flat, F and A flat make the minor seventh, and the C on top makes it a ninth. It is the ii chord of A flat and a richer stand in for B flat minor anywhere.

The upper four notes spell Dbmaj7 on their own, which is why the split works: left hand B flat, right hand a plain Dbmaj7, and together they are Bbm9. This is the everyday minor of soul and jazz in the flat keys.

Bbm9 vs Bbm7

Bbm9 adds a C to the four notes of Bbm7. The seventh chord is smooth already; the ninth puts air above it.

Under the hand they are nearly the same chord. The C lands a ninth above the root, so the ninth version usually means two hands where the seventh needed one.
