So I'm a beginning bass player, and one of my biggest problems is holding the damn thing. I've tried shifting the bass to different angles and playing both sitting down and standing up, and my elbow starts to hurt, almost immediately. It's a pretty dull pain and doesn't go away until I stop playing. Also, trying to get all of my fingers down on the fretboard only makes it worse and make my hand hurt. This is a really frustrating problem because I really want to learn to play, but even holding it correctly hurts me, and my hand is at such a weird angle that I can barely move my fingers let alone press the strings. Literally, the only position I've found so far that I can play with no pain at all, and able to actually move my fingers and press the strings is when the bass is almost upright. Remember I'm a beginner, so I'd prefer tips on how I can train my left arm to be more comfortable with the playing position.
