F Phrygian scale on the guitar fretboard

The F Phrygian scale is made of F (the root), Gb (minor second), Ab (minor third), Bb (perfect fourth), C (perfect fifth), Db (minor sixth) and Eb (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.
