So I've jammed with this singer and drummer a few times now. They were looking to start up a band just for fun, writing original stuff, and needed a bassist and maybe a guitarist (the singer can strum chords while he's singing, but that's about it). They seemed like decent guys, but I didn't really have anything in common with them, either music taste-wise or personality-wise, so it wasn't a surprise when at a jam today the singer said "Look, you're a good guy, and we don't have any problems with you personally, but we don't think you fit in with the idea of the band we're trying to create." I think to myself, that's cool. Not like this band will gig for quite a while, so why spend a year not getting paid to play stuff you don't like? I'm thinking the same thing, we talk for a while, I'm out of the band, if I know any bass players I think would fit better, I'll send them this way, the singer and drummer will send other musicians my way, etc. It's all cool at this point. Then, after I pack up all my gear and get ready to leave, the singer says this: "Oh, before you go..." Hands me two sheets of paper, one blank notation, the other blank tab. "I just need you to write down all your basslines. In notation if the new guy can read it, in tab if he can't." I politely refuse, saying how I wrote all the basslines, and I'd really prefer the new guy to come up with his own, since I'm not going to get any money or recognition from this. He says, "But all your bass lines came after hearing the drums and chord progressions, so you wouldn't have written them without, so, in effect, WE own those basslines. I usually try not to burn my bridges, but this angered me quite a bit. So, naturally, I replied that if he wants to write them down, I can't really stop him, but I'm not going to help give away my work. He says "I can't write them out; I don't know them! So you have to write them out for me before you leave." This is the point where the drummer started laughing at the singer. I got to keep my basslines to myself.
