As we already know from the minor pentatonic scale theory lesson, the B flat minor pentatonic scale has 5 notes (which are derived from the minor scale). This is the formula for the minor pentatonic, as well as its notes in the key of Bb.
|Minor pentatonic scale||1||b3||4||5||b7|
|Bb minor pentatonic notes||Bb||Db||Eb||F||Ab|
Here is a guitar fretboard diagram of the Bb minor pentatonic scale. Notice that the notes repeat along the entire width of the fretboard, based on the formula for the scale.
To help us visualize the scale, there are 5 minor pentatonic scale shapes.
Here they are, applied to the Bb minor pentatonic.
