Ab Phrygian scale on the guitar fretboard

The Ab Phrygian scale is made of Ab (the root), Bbb (minor second), Cb (minor third), Db (perfect fourth), Eb (perfect fifth), Fb (minor sixth) and Gb (minor seventh). The fretboard shows every one of them across the neck in standard tuning (E A D G B E), and plays them back so you can hear the scale.

The Phrygian mode is the third mode of the major scale, a minor scale with a lowered second. That lowered second sits a semitone above the root on the neck. It shares its notes with a major scale a major third below.
