B Blues Scale
The B Blues scale is built from the notes B, D, E, E#, F#, and A. The diagram below maps every one of those notes across the guitar neck, from the open strings up to the 12th fret, with the root B highlighted.
The blues scale is the minor pentatonic plus one flat-five blue note, the extra note that gives it that crying, vocal sound.
