B Pentatonic Minor scale on the guitar fretboard

The B Pentatonic Minor scale is made of B (the root), D (minor third), E (perfect fourth), F# (perfect fifth) and A (minor seventh). The fretboard shows every one of them across the neck in standard tuning (E A D G B E), and plays them back so you can hear the scale.

The minor pentatonic scale has five notes, the root, a minor third, a fourth, a fifth and a minor seventh. It is a subset of the natural minor, so its shapes sit inside the larger scale on the neck. Add a flat five and you reach the blues scale.
