Ab Lydian Scale in Open C Tuning

Ab Lydian Scale in Open C Tuning shows the same ab lydian scale pitch classes across 6 strings tuned C G C G C E. The tuning changes where the same pitch classes sit across the fretboard.

Scale notes: Ab, Bb, C, D, Eb, F, G
Formula: 1 2 3 #4 5 6 7
Semitones: 0 2 4 6 7 9 11
Parent scale: Eb major
Tuning: C G C G C E
Strings: 6
Open pitch range: C2 to E4
24-fret range: C2 to E6

Open strings and root positions

5 of the 6 open strings belong to Ab Lydian Scale: string 6 C (3), string 5 G (7), string 4 C (3), string 3 G (7), and string 2 C (3). None of those open-string tones is the Ab root, so the root must be fretted on every string.

Low-string pattern

Practice this tuning-specific layout

Play Ab Lydian Scale on the low C string at frets 0, 2, 3, 5, 7, 8, and 10, saying each note name and degree aloud.
Build a phrase that lets C 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 6 through 1 at frets 8, 1, 8, 1, 8, and 4, adding the nearest scale tone between each pair of roots.
