Once again, a 'what key' thread. Not because I'm lazy, but because I'm theoretically challenged. I've read the 'What Chords Are In What Key' article twice, and I still don't get it. I've given up on learning for now, but I still need to know in what key this song is, and what scales I could use.. So if any of you guys could help me, that'd be great!

Tell me who's that writin'...
Take a look at the link in my signature. I hope it's not too advanced for you; I'm not sure what you do and don't know. It provides a method that is more definitive than a "what notes go with what key" approach. I have a progression on hand that uses all 12 notes, so the only method for determining the key of it is with the method described in the link. In the case of the song you posted, which I haven't looked at in preference to teaching a man to fish, it's probably much more simple.
i don't know why i feel so dry
Thanks for the replies.. To me, it seems to resolve on G, but I might be completely wrong about this. ... So I guess this gives me the key of Gm?
