B C D E F G A (1 ♭2 ♭3 4 ♭5 ♭6 ♭7)
The vii° chord's scale. Rarely home; mostly theory.
Positions: the five CAGED shapes, each built around a pentatonic box with the other two notes slotted in. One finger per fret, with the odd stretch. Each one shares its edge notes with the next. Dots show scale degrees: 1 is the root.
Three-notes-per-string shapes (7 of them) are on the interactive fretboard.
