This is probably asked alot of times but I just do not seem to be able to figure it out by myself. The quetion is simple: What is the first chord of Prince's Purple Rain. I know a lot of people will say (and in fact all transcripts I seen say) it's a plain F. But it's not.

For the people who doubt it; Play Purple Rain and play an F at the beginning and you'll hear Prince plays sort of an F. It's an F something. But I really like to know what the something is.
I'll try them, I tell you this has been bugging me for the longest time specially since I USED to know

Anyway sorry for the off topic posting. New around here. I'll pay attention better next time
