Ab Locrian Scale in 7-String Drop G Tuning

Ab Locrian Scale in 7-String Drop G Tuning shows the same ab locrian scale pitch classes across 7 strings tuned G D G C F A D. The seventh string extends the pattern below a six-string layout while keeping the upper strings familiar.

Scale notes: Ab, Bbb, Cb, Db, Ebb, Fb, Gb
Formula: 1 b2 b3 4 b5 b6 b7
Semitones: 0 1 3 5 6 8 10
Parent scale: A major
Tuning: G D G C F A D
Strings: 7
Open pitch range: G1 to D4
24-fret range: G1 to D6

Open strings and root positions

3 of the 7 open strings belong to Ab Locrian Scale: string 6 Ebb (b5), string 2 Bbb (b2), and string 1 Ebb (b5). None of those open-string tones is the Ab root, so the root must be fretted on every string.

Low-string pattern

On the lowest G string, the first-octave scale pattern falls at frets 1, 2, 4, 6, 7, 9, and 11, with the Ab root at fret 1. On the highest D string, the first Ab is at fret 6.

Practice this tuning-specific layout

Play Ab Locrian Scale on the low G string at frets 1, 2, 4, 6, 7, 9, and 11, saying each note name and degree aloud.
Build a phrase that lets Ebb on open string 6 ring, then connect it to the nearest Ab root and two other scale tones.
Connect the Ab root positions on strings 7 through 1 at frets 1, 6, 1, 8, 3, 11, and 6, adding the nearest scale tone between each pair of roots.
