D Phrygian Scale in Drop C# Tuning

D Phrygian Scale in Drop C# Tuning shows the same d phrygian 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: D, Eb, F, G, A, Bb, C
Formula: 1 b2 b3 4 5 b6 b7
Semitones: 0 1 3 5 7 8 10
Parent scale: Bb 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

2 of the 6 open strings belong to D Phrygian Scale: string 2 Bb (b6) and string 1 Eb (b2). 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, 8, 9, and 11, with the D root at fret 1. On the highest D# string, the first D is at fret 11.

Practice this tuning-specific layout

Play D Phrygian Scale on the low C# string at frets 1, 2, 4, 6, 8, 9, and 11, saying each note name and degree aloud.
Build a phrase that lets Bb on open string 2 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 1, 6, 1, 8, 4, and 11, adding the nearest scale tone between each pair of roots.
