So, a kid at my school recently asked me to play guitar with him, in a two piece type of thing, he's amazing so I said yes of course, and I have a CD of his piano parts, and I have to write some guitar stuff, but I'm having big trouble taking his parts that I hear, and figuring out what chord it is, he plays a lot of crazy stuff, and he plays by ear, so I cant ask him to name the chords, because he doesnt even know...anyone have any suggestions at all? Anything would be appreciated, thanks.
Just improvise over it, eventually you'll find a scale that fits.
Yeah just play over it and you'll find something that works. It will be in a key, you just have to find it.
Work out as much as you can... Then ask him what the other chords are :P
PLAY DISSANANT!!!! that's what all the cool kids do
