i've been asking around forums as to how to get rid of unwanted string noises when i lift my finger off the string. there's been mainly 2 suggestions, fret hand muting and light palm muting. i've been told by some people to mute unused strings with my fret hand. on the other hand, i've also been told to float my palm lightly over the strings near the edge of the bridge to cut unwanted noise. so which method should i use to cut noise? also, i've noticed that my single note lines sometimes sound very sloppy because the notes seem to overlap each other and after a while it sounds like they're all ringing together. how do you get a tight concentrated sound when playing? will fret hand muting or palm muting help me to achieve a tighter more concentrated sound?
