A Major (Ionian) Scale in Open G Tuning

A Major (Ionian) Scale in Open G Tuning shows the same a major (ionian) 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: A, B, C#, D, E, F#, G#
Formula: 1 2 3 4 5 6 7
Semitones: 0 2 4 5 7 9 11
Parent scale: A 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

4 of the 6 open strings belong to A Major (Ionian) Scale: string 6 D (4), string 4 D (4), string 2 B (2), and string 1 D (4). None of those open-string tones is the A 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 0, 2, 4, 6, 7, 9, and 11, with the A root at fret 7. On the highest D string, the first A is at fret 7.

Practice this tuning-specific layout

Play A Major (Ionian) Scale on the low D string at frets 0, 2, 4, 6, 7, 9, and 11, saying each note name and degree aloud.
Build a phrase that lets D on open string 6 ring, then connect it to the nearest A root and two other scale tones.
Connect the A root positions on strings 6 through 1 at frets 7, 2, 7, 2, 10, and 7, adding the nearest scale tone between each pair of roots.
