I have been playing slap for quite a while and feel like I have it down pretty well. But today I noticed that I have to try hard to make slap notes ring out for a while when it is not on the E string. This is because I naturally rest the palm (near the wrist) of my right hand on the strings mutting them. Palm muting I think, right? While this does seem to help keep everything clean sounding it makes it hard for me to have one note keep ringing. So I started trying to play without resting my hand at all. It was a little more difficult and I just feel less accurate because I have no "anchor". So I guess my question is if it is better to play slap without "anchoring" your hand anywhere and just keeping it floating or not. And whether it is good to do either depending on the song.
