Ab Mixolydian Scale in 7-String Drop G Tuning

Ab Mixolydian Scale in 7-String Drop G Tuning shows the same ab mixolydian 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.

Formula: 1 2 3 4 5 6 b7
Semitones: 0 2 4 5 7 9 10
Parent scale: Db 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

2 of the 7 open strings belong to Ab Mixolydian Scale: string 4 C (3) and string 3 F (6). None of those open-string tones is the Ab root, so the root must be fretted on every string.

Practice this tuning-specific layout

Play Ab Mixolydian Scale on the low G string at frets 1, 3, 5, 6, 8, 10, and 11, saying each note name and degree aloud.
Build a phrase that lets C on open string 4 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.
