piano chord
B♭sus2
B♭1C2F5
The third replaced by the second. Nothing in it decides between major and minor.
Written the other way round it is A♯sus2 — the same twelve keys on a piano, a different piece of notation.
What is true of it
B♭sus2 is B♭, C and F — 1, 2 and 5 counted from B♭.
These are also the notes of Fsus4/B♭. Which name is right depends on what is underneath and what came before — the notes alone do not decide.
