Super Locrian bb7 (Ultra Locrian) on Guitar
The Super Locrian bb7 scale is the seventh mode of harmonic minor: 1 b2 b3 b4 b5 b6 bb7. Some players call it Ultra Locrian.
The double-flat seventh has the pitch of a major sixth but is spelled as a seventh, which makes the tonic chord a diminished seventh. Pick a key below for the notes, fretboard patterns and player.

Structure
How the super locrian bb7 scale is built:
The super locrian bb7 scale is built from the degrees 1 b2 b3 b4 b5 b6 bb7, which gives the step pattern H-W-H-W-W-H-W+H (W = whole step, H = half step).
Counting in semitones from the root: 0, 1, 3, 4, 6, 8, 9. That makes it a 7-note scale.
It is mode 7 of the Harmonic Minor Scale, so both scales share the same notes from a different starting point.
It is also known as Ultra Locrian.
