C# Major (Ionian) Scale in Open C Tuning

C# Major (Ionian) Scale in Open C Tuning shows the same c# major (ionian) 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: 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: 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

3 of the 6 open strings belong to C# Major (Ionian) Scale: string 6 B# (7), string 4 B# (7), and string 2 B# (7). 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 C string, the first-octave scale pattern falls at frets 0, 1, 3, 5, 6, 8, and 10, with the C# root at fret 1. On the highest E string, the first C# is at fret 9.

Practice this tuning-specific layout

Play C# Major (Ionian) Scale on the low C string at frets 0, 1, 3, 5, 6, 8, and 10, saying each note name and degree aloud.
Build a phrase that lets B# on open string 6 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 1, 6, 1, 6, 1, and 9, adding the nearest scale tone between each pair of roots.
