guitar scale
F Phrygian dominant
The fifth mode of harmonic minor: a flat second over a major third, so the step from the second to the third is a step and a half.
Written out
Every accidental is written in, rather than left to a key signature, so the letters can be read one at a time.
The step pattern
What is true of it
F Phrygian dominant is F, G♭, A, B♭, C, D♭ and E♭, and back to F.
Its steps are H – W+H – H – W – H – W – W, where W is a whole step and H a half.
On the same tonic, F Phrygian differs from it by exactly one note.
Across the first twelve frets of the guitar its notes fall in 43 places, which is what makes a scale a shape rather than a list.
