I've seen many bass players and read in some books that after you 'strike' a string, your finger should rest on the string below it (to mute it or whatever). The way I play, my fingers just fly back up towards my palm without hitting any other string (in a circular motion), but I'm starting to get a lot of aches in my finger joints if I bend them. If I do try to play the way the books say, I cant play fast enough or I create a lot of unwanted noise. I could really use any suggestions. Has anyone had a similar problem who could help? Thanks in advance!
