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