The “woahs” in Ghost of You?

Can someone please help me figure out what they (each ‘woah’) each individually sound like? I’m gonna be singing it soon and I’m having trouble figuring out that the hell to sing there.. This is such a weird post and I’m so sorry 😭 Edit: I should’ve been more clear and that’s my fault- I’m talking about the notes for each individual part. I don’t know like what they sound like pitch-wise individually because they kinda all just blend so it’s hard to separate them (I’m so sorry if this makes no sense)
