I know nothing about music, but I have a lot of experience doing my know-nothing thing. If you know what I mean. Anyway. The other day I was recording a bass part I'd composed earlier that afternoon. It was for a cover of a song by Emerson Lake & Palmer called Battlefield. I do not know the original song and I chose to keep it that way by deliberately not listening to it. I just listened to the scratch tracks I was given, composed something, showed up to record it that night. Here's the thing. I'm playing, we're recording, everything's going good. Producer/guitarist is telling me he really digs what I'm doing. Later on, he picks up a guitar to do another track on the song. He remarks that he just realized the key! Haha! It's E minor! At this my blood runs cold. I'd been hitting the major 3rd of that E--the G#--twice through every verse of the song. I immediately seek clarification. And thus starts a weird discussion where we verify that the E is minor...but that the major 3rd sounds okay in this composition I recorded. More than ok, it sounds wrong to do it with the minor 3rd. What's up with that? Hopefully he'll send me a copy of the track so far so I can share it with you on sound cloud. But if anyone wants to hazzard a guess as to what's going on here, please do!
