In the following acoustic guitar lesson, you will learn how to play the Bbm9 Guitar Chord (also known as A#m9, B Flat Minor 9, B Flat Minor 9th, A Sharp Minor 9).
Before jumping right to the chord charts, lets learn a bit more about the theory behind this chord.
The Bbm9 chord is formed from the Bb Major Scale: Bb C, D, Eb, F, G, and A. To find the notes to pull out of the scale, we use the formula: 1,b3, 5, b7, 9. This means that we take the 1st, flattened 3rd, 5th, flattened 7th and 9th steps of the Bb Major Scale. In other words, the notes Bb, Db, F, Ab and C.
The “flattened 3rd” means that we take the 3rd step of the Bb Major scale and flatten it by 1/2 step giving us our “Db”. The “flattened 7th” means that we take the 7th step of the same scale and flatten it by 1/2 step giving us our “Ab”.
There are three Bbm9 chord charts below for you work on. These chords are a little challenging, but don’t give up . Keep working on them and eventually they will become second nature.
Here is a key that will help you read the charts:
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.
