C# Lydian Scale in Open G Tuning

C# Lydian Scale in Open G Tuning shows the same c# lydian scale pitch classes across 6 strings tuned D G D G B D. The tuning changes where the same pitch classes sit across the fretboard.

Scale notes: C#, D#, E#, F##, G#, A#, B#
Formula: 1 2 3 #4 5 6 7
Semitones: 0 2 4 6 7 9 11
Parent scale: G# major
Tuning: D G D G B D
Strings: 6
Open pitch range: D2 to D4
24-fret range: D2 to D6

Open strings and root positions

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

Low-string pattern

On the lowest D string, the first-octave scale pattern falls at frets 1, 3, 5, 6, 8, 10, and 11, with the C# root at fret 11. On the highest D string, the first C# is at fret 11.

Practice this tuning-specific layout

Play C# Lydian Scale on the low D string at frets 1, 3, 5, 6, 8, 10, and 11, saying each note name and degree aloud.
Build a phrase that lets F## on open string 5 ring, then connect it to the nearest C# root and two other scale tones.
Connect the C# root positions on strings 6 through 1 at frets 11, 6, 11, 6, 2, and 11, adding the nearest scale tone between each pair of roots.
