D Major (Ionian) Scale in Open C Tuning

D Major (Ionian) Scale in Open C Tuning shows the same d 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: D, E, F#, G, A, B, C#
Formula: 1 2 3 4 5 6 7
Semitones: 0 2 4 5 7 9 11
Parent scale: D 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 D Major (Ionian) Scale: string 5 G (4), string 3 G (4), and string 1 E (2). None of those open-string tones is the D 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 1, 2, 4, 6, 7, 9, and 11, with the D root at fret 2. On the highest E string, the first D is at fret 10.

Practice this tuning-specific layout

Play D Major (Ionian) Scale on the low C string at frets 1, 2, 4, 6, 7, 9, and 11, saying each note name and degree aloud.
Build a phrase that lets G on open string 5 ring, then connect it to the nearest D root and two other scale tones.
Connect the D root positions on strings 6 through 1 at frets 2, 7, 2, 7, 2, and 10, adding the nearest scale tone between each pair of roots.
