piano chord
Bsus2
B1C♯2F♯5
The third replaced by the second. Nothing in it decides between major and minor.
What is true of it
Bsus2 is B, C♯ and F♯ — 1, 2 and 5 counted from B.
These are also the notes of F♯sus4/B and G♭sus4/B. Which name is right depends on what is underneath and what came before — the notes alone do not decide.
