piano chord
Esus2
E1F♯2B5
The third replaced by the second. Nothing in it decides between major and minor.
What is true of it
Esus2 is E, F♯ and B — 1, 2 and 5 counted from E.
These are also the notes of Bsus4/E. Which name is right depends on what is underneath and what came before — the notes alone do not decide.
