Why can't I do it?
Sitting down, I can jam through some Rush, Chili Peppers, Jamiroquai, Chic and even a couple of Level 42 songs.
Standing up? I can barely play along with a Nirvana song without slopping it up. I'm thinking it must be something to do with hand position, but my instrument is at the same position as it is when I sit down. What on earth could the problem be? I can't get any speed or control in my plucking, can't get the nice ticklish light touch I use for fast playing. If I raise the bass up to a position where it's so high I could pluck with my tongue, I do a little better, but my left hand is suddenly in an uncomfortable position where I can't get freedom of movement.
