Electric Bass: Ab Phrygian Over the Changes

Ab Phrygian runs 7 notes to the octave, laid out here on EADG with every Ab 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 electric bass can hold a note long enough for it to be heard as a choice rather than a step, so a scale here is read for its strong tones first and its passing tones second.

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.
