A Super Locrian ♭♭7 (Ultralocrian) on the Guitar Fretboard
The notes of Super Locrian ♭♭7 (Ultralocrian) repeat across the guitar fretboard in connected positions. Use the shape below to identify root notes, scale degrees, and neighboring shapes.

How to practice this shape
- Start on the root — A at fret 5 on the E string. Play up to the highest note in the shape, then back down, staying inside frets 5–14.
- Your hand shifts 5 times as you cross strings: E→A (+1), A→D (+1), D→G (+1), G→B (+2), B→E (+1). Those crossings — not the notes — are what this position is really asking you to learn.
- Once it feels automatic, move on to the next of the 2 shapes — together they cover the whole neck, and the same pattern repeats from there.
