Ab Dorian Scale in 7-String Standard Tuning

Ab Dorian Scale in 7-String Standard Tuning shows the same ab dorian scale pitch classes across 7 strings tuned B E A D G B E. The seventh string extends the pattern below a six-string layout while keeping the upper strings familiar.

Formula: 1 2 b3 4 5 6 b7
Semitones: 0 2 3 5 7 9 10
Parent scale: Gb major
Tuning: B E A D G B E
Strings: 7
Open pitch range: B1 to E4
24-fret range: B1 to E6

Open strings and root positions

2 of the 7 open strings belong to Ab Dorian Scale: string 7 Cb (b3) and string 2 Cb (b3). 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 Dorian Scale on the low B string at frets 0, 2, 4, 6, 7, 9, and 11, saying each note name and degree aloud.
Build a phrase that lets Cb on open string 7 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 9, 4, 11, 6, 1, 9, and 4, adding the nearest scale tone between each pair of roots.
