So I've been trying to get a music project started with my brother, who is a guitarist. He is a phenomenal player; a great soloist and everything. The problem, however, is working with him. He has been playing for 15 years and still doesn't know his keys. He honestly couldn't play something in the key of G even if his life depended on it. This has been a serious problem for writing, since he can't find lead to match any of the chords that he plays. It just sounds.. jumbled. However, when I try telling him this, he gets boisterous and defensive. Then resorts to yelling, cursing, bigoted insults, (begins with f, rhymes with baguette) and sometimes threats if he takes it far enough. I try teaching him, but he assumes that just because he has been playing for 15 years and I have been playing for 3 that he knows more than me by default. He always has this "my way or the highway" attitude that just kills it for everyone. To him, everything has to be metal. Everything has to have distortion. And most importantly for him, everything must have double bass drums. But it doesn't stop there.. I was using Guitar Pro to write out a riff that he gave me. A sort of heavy blues riff. The disagreement came when he tried telling me that his riff was in 4/4. I was a bit bothered by this, because 1) he doesn't know music theory whilst I do, and 2) the riff he made was subdivided into sections of 14/8, then 10/8, then 9/8, then 12/8, then 3/4, then 4/4, then 12/8. I even counted it off for him by physically clapping and it didn't fit. He then got frustrated, called me some derogatory names, then shut the door and left. Eventually he came to his senses when our drummer finally had confirmed that he wasn't writing in 4/4. I can tell that he too is getting tired of my brother's unwillingness to compromise on extremely minor ideas that he knows nothing about and his overinflated ego that makes him think that he is the best guitarist in this town. Sure, he can solo, but what's the point if you don't know what you're doing? So TB, what should I do? Should I continue trying to work with my brother and try teaching him to the best of my abilities, or should I just leave him behind for someone who is going to be less argumentative? Also, how do you deal with guitarists that act this way? Any stories worth sharing are always welcome.
