Bass Fills With B Phrygian

B Phrygian runs 7 notes to the octave. Below it is laid onto this chair's EADG fretboard with every B marked, because what a fill needs mid-song is not the pattern — it is where the root is when the chord changes under it.

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 bass rarely takes a fill, and that is precisely why these matter: the notes between one root and the next come out of the scale, and a walk that lands wrong is the loudest mistake in the mix.

Play it slowly against the audio until the shape stops being a shape, then take it to a song in B and let the melody pick its own notes out of it.
