C# Major (Ionian) Scale in 7-String Drop G Tuning

C# Major (Ionian) Scale in 7-String Drop G Tuning shows the same c# major (ionian) 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: C#, D#, E#, F#, G#, A#, B#
Formula: 1 2 3 4 5 6 7
Semitones: 0 2 4 5 7 9 11
Parent scale: C# 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 C# Major (Ionian) Scale: string 4 B# (7) and string 3 E# (3). 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 G string, the first-octave scale pattern falls at frets 1, 3, 5, 6, 8, 10, and 11, with the C# root at fret 6. On the highest D string, the first C# is at fret 11.

Practice this tuning-specific layout

Play C# Major (Ionian) 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 B# on open string 4 ring, then connect it to the nearest C# root and two other scale tones.
Connect the C# root positions on strings 7 through 1 at frets 6, 11, 6, 1, 8, 4, and 11, adding the nearest scale tone between each pair of roots.
