C# Phrygian scale on the guitar fretboard

The C# Phrygian scale is made of C# (the root), D (minor second), E (minor third), F# (perfect fourth), G# (perfect fifth), A (minor sixth) and B (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.
