Bb Phrygian Dominant Scale

What is the Bb 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 Bb Phrygian Dominant Scale lays out on the fretboard. This scale is enharmonically equivalent to A# Phrygian Dominant.

Notes and Positions

Spanish/Middle Eastern flavor; 5th mode of harmonic minor. On bass, this scale becomes a toolkit for strong roots, passing tones, and melodic fills that still support the groove. Think in root-on-E and root-on-A boxes, then adapt the same notes for 5-string bass when the low B string gives you another root below the pattern. In the key of Bb, the notes are: Bb, Cb, D, Eb, F, Gb, Ab.

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.

Build two-bar bass lines that return to the root before experimenting with wider melodic movement. Use the interactive fretboard above to spot repeats of the same note on different strings and frets.
