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