You can either skip right down to the guitar chord charts below to learn how to play this chord, or stick around for a quick bit of theory on how to form this chord.
This chord is made up of the 1, 3, 5, b7 and 9 positions of the Bb Major Scale: Bb C, D, Eb, F, G, and A. This gives us the notes Bb, D, F, Ab and C. The “b7” symbol means that we take the 7th note of the Bb major scale (A) and flatten it by 1/2 step. The 7th note of this scale is an A, so when we flatten it by 1/2 step, we arrive at our “Ab” note.
There are three Bbm9 chord charts below for you to get under your fingers. These chords are a little challenging, but don’t give up if you are having a difficult time. Keep practicing and you will eventually be able to play these with ease.

Everything on the above chart should be self explanatory, except for the last three in the third column. They may need a bit of explaining. The O, or open symbol, simply means that you do not press down on any notes on that string. The X means you do not strum that particular string. The Barre symbol means you need to barre that particular fret. When you barre a fret you are pressing down on multiple strings at the same time with one finger.
