piano chord
F♯sus2
F♯1G♯2C♯5
The third replaced by the second. Nothing in it decides between major and minor.
Written the other way round it is G♭sus2 — the same twelve keys on a piano, a different piece of notation.
What is true of it
F♯sus2 is F♯, G♯ and C♯ — 1, 2 and 5 counted from F♯.
These are also the notes of C♯sus4/F♯ and D♭sus4/F♯. Which name is right depends on what is underneath and what came before — the notes alone do not decide.
