Heres my situation: 16 years old, high school, in a band with my friends for fun, get some gigs, something to do. We have been playing together for about a year and a half and at the moment we have some pretty decent original material, funk alternative, experimental type stuff. Bass to me is a great hobby and im always on Talkbass trying to learn more. My knowledge of theory is growing although its not where id like it to be (if anyone knows some REALLY good online sources for information thatd be awesome). Technically, im a pretty accomplished player, im proud of where i am at the moment. My drummer really likes drums and is also always at a drummers forum learning more and he loves to accessorize on his kit and stuff and learn new things. He has taken a few lessons and hes quite good. My guitarist/friend, not so much. No lessons, no music theory whatsoever. (barely knows the names of the strings) Doesnt even know that the strings are tuned in fifths except for the G/B is a 4th, etc. Basic stuff. He doesnt practice much and is okay at playing he just doesnt know what hes playing. As much as i try he wont learn any theory at all. It makes playing together very hard because i either have to write the guitar part or i have to look at his hands to see literally what frets hes playing because he doesnt know what notes they are. I feel this is making me not get any better because i cant work with jamming in key with him and stuff like that, his lack of knowledge is slowing me and (i feel) the drummer down. Today he was over and basically told me he doesnt give a crap about theory and its not important, as long as he can play. I told him hes wrong and i dont enjoy playing with him at the current situation. What should i do? EDIT: brain fart, tuned in fourths?
