The F♯ Phrygian scale has 7 notes: F♯ – G – A – B – C♯ – D – E. Phrygian is a minor scale with a ♭2, one fret above the root. That dark half step gives it a Spanish, heavy feel. In Indian music it is Bhairavi thaat.
F♯ and G♭ are the same pitch, so this page covers both names; the notes are spelled from F♯, the way the key is usually written. Compared with the F♯ major scale it has ♭2 (G instead of G♯), ♭3 (A instead of A♯), ♭6 (D instead of D♯), ♭7 (E instead of E♯).
The explorer above is set to F♯ Phrygian: the whole neck is mapped, and you can zoom into any of its 7 positions, change the labels to degrees or fingers, and hear it up, down and in patterns.
