so, this is kind of embarassing, but im a total noob to technique on bass. ive been playing for 3 years, ive been in a band for almost that whole time, and up until now, technique hasnt been a problem for me, so i just assumed i was doing it right. there werent any stickies in this forum, and im not sure what to search for, so i decided to ask for advice. recently, my band tried to record instruments separately. lets just say it exposed a lot of things about my playing that surprised them, and me, for that matter. i wear my bass farily high, im right handed, and i play a 4 string. ill break it down into all the separate problems i think im having. my first one would be with my fretting (left) hand. mostly, i keep my thumb up by the top of the fretboard, sometimes with it hanging over the top if i play on the d and g strings and need to mute the e and a strings. recently, ive been trying to keep my thumb on the back of the fretboard (like my guitarists), near the stripe on the back, but that makes it impossible to mute strings that i dont use. i also have problems with releasing notes on the fretting hand. if i want to play short, stacato (sp?) quarter notes or something, i play the note, then release it with my fretting hand, and it always gets this awkward buzz right at the end of the note. i wish i could record it, but alas, i dont have a computer mic . should i be muting with my playing (right) hand, instead of my fretting one? i tried that, but its really awkward. also, i have trouble with my playing hand. i used to play with my fingers at about a 45 degree angle to the strings, but i would get horrible fretbuzz if i didnt play extremely lightly. im trying to play closer to perpendicular now, but it still seems like i get a lot of fretbuzz. my last, and least important problem, is with finger alternation. i play with 2 fingers on my playing hand, and lets say i had to play a note on the g string, then on the d string in rapid succession. i would play the note on the g with my index finger, then instead of switching to use my middle finger on the d, i would use the index finger that had just come to rest on the d. (if that makes any sense to anyone...). so if i had to play 4 notes across all 4 strings, i would use just the index finger if i was coming from the g to the e string, but if i was going down, from the e to the g string, i would use correct finger alternation. is there anything wrong with this, because it feels way more natural this way, and i can play way faster like that. if anyone can make any sense of the gibberish i just typed, and could lend me some advice, or point me in the direction of some helpful threads, id appreciate it.
