A Altered Scale (Super Locrian) on the Guitar Fretboard
The notes of Altered Scale (Super Locrian) repeat across the guitar fretboard in connected positions. Use the shape below to identify root notes, scale degrees, and neighboring shapes.
- Frets 5–15 (span 10 frets)
- Lowest note A, highest note G
- 3 A root notes, on the E string (fret 5), D string (fret 7), B string (fret 10)
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 5–15.
- 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.
