A Mixolydian Scale in Drop C# Tuning

A Mixolydian Scale in Drop C# Tuning shows the same a mixolydian scale pitch classes across 6 strings tuned C# G# C# F# A# 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 b7
Semitones: 0 2 4 5 7 9 10
Parent scale: D major
Tuning: C# G# C# F# A# D#
Strings: 6
Open pitch range: C#2 to D#4
24-fret range: C#2 to D#6

Open strings and root positions

3 of the 6 open strings belong to A Mixolydian Scale: string 6 C# (3), string 4 C# (3), and string 3 F# (6). 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 C# string, the first-octave scale pattern falls at frets 0, 1, 3, 5, 6, 8, and 10, with the A root at fret 8. On the highest D# string, the first A is at fret 6.

Practice this tuning-specific layout

Play A Mixolydian 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 C# 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 8, 1, 8, 3, 11, and 6, adding the nearest scale tone between each pair of roots.
