F# Blues scale on the guitar fretboard

The F# Blues scale is made of F# (the root), A (minor third), B (perfect fourth), B# (augmented fourth), C# (perfect fifth) and E (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 blues scale listed here has six notes, with a raised fourth between the fourth and the fifth. The map shows how that one extra note joins the minor pentatonic shapes on the neck. It is a close relative of the minor pentatonic.
