Piano: B Phrygian Over the Changes
Where B Phrygian lies at this seat, and what a chorus takes out of it.
B Phrygian runs 7 notes to the octave, laid out here across 88 keys with every B flagged. Mid-chorus the pattern is not what you need; where the root is when the chord changes underneath you is.
Very dark minor with a half-step above the tonic. Spanish, Flamenco, and metal flavor — exotic, tense, and mysterious.
Heard in: Flamenco, metal, dark film scores — Carlos Santana solos, Joe Satriani's "War", Moorish and Andalusian music.
The right hand takes the line and the left keeps stating the chord under it, which makes a scale at this seat a two-handed problem: the notes have to work against a voicing you are choosing at the same time.
Play it slowly against the audio until it stops being a shape, then put it over two bars of a form and let the chord tones decide which of the notes you actually keep.
