What makes G♯ Locrian different
Locrian is the only mode of the major scale with a diminished fifth, so its tonic chord is a diminished triad rather than a major or minor one. That flat fifth is the one note separating it from Phrygian. Without a perfect fifth the tonic never sounds at rest, which is why whole pieces in Locrian are rare and the mode lives mostly in theory, over half-diminished chords in jazz, and in metal riffs. It's the seventh mode of the major scale, so it shares its notes with the major scale a half step above its root. On G♯, G♯ Locrian has D where G♯ Phrygian has D♯; every other note is shared with G♯ Phrygian (G♯ A B C♯ D♯ E F♯).
