What is the G Phrygian Dominant Scale?
Phrygian dominant is the fifth mode of the harmonic minor scale, and it sounds like Phrygian mode but with a major 3rd instead of a minor 3rd. That combination of the exotic ♭2 with a bright major 3rd is the defining sound of flamenco, Middle Eastern music, and the V chord resolving to a minor tonic in classical harmony. Here's how the G Phrygian Dominant Scale lays out on the fretboard.
Notes and Positions
Spanish/Middle Eastern flavor; 5th mode of harmonic minor. On guitar, the same scale tones repeat in multiple positions, so the real goal is learning how to connect shapes up and down the neck. Use the CAGED boxes as smaller practice areas before linking the full fretboard. In the key of G, the notes are: G, Ab, B, C, D, Eb, F.
How to Use It
You'll often hear it in Flamenco, Metal, and Middle Eastern. A good way to internalize the sound is to sing the root, then sing a few scale degrees before you play them.
Alternate between ascending patterns and short musical phrases so it doesn't become a "scale exercise" only. Use the interactive fretboard above to spot repeats of the same note on different strings and frets.
