F Phrygian Scale in Drop C# Tuning

F Phrygian Scale in Drop C# Tuning shows the same f 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: F, Gb, Ab, Bb, C, Db, Eb
Formula: 1 b2 b3 4 5 b6 b7
Semitones: 0 1 3 5 7 8 10
Parent scale: Db 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

6 of the 6 open strings belong to F Phrygian Scale: string 6 Db (b6), string 5 Ab (b3), string 4 Db (b6), string 3 Gb (b2), string 2 Bb (4), and string 1 Eb (b7). None of those open-string tones is the F 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, 2, 4, 5, 7, 9, and 11, with the F root at fret 4. On the highest D# string, the first F is at fret 2.

Practice this tuning-specific layout

Play F Phrygian Scale on the low C# string at frets 0, 2, 4, 5, 7, 9, and 11, saying each note name and degree aloud.
Build a phrase that lets Db on open string 6 ring, then connect it to the nearest F root and two other scale tones.
Connect the F root positions on strings 6 through 1 at frets 4, 9, 4, 11, 7, and 2, adding the nearest scale tone between each pair of roots.
