OK, I've been listening a bit to Rocco and been trying to cop his feel. I can't, which is no suprise, but I'm working on it. The only way I can get that sound is to use my right hand fingers to stop the string ringing, leaving the left hand out of the muting picture - it just frets the notes as in legato playing. I stop the ringing string with the finger other than the one I just plucked it with, and when it comes time to play the next note the playing finger is right there on the string - unless the next note is on a different string, in which case things get messy. How does everybody else deal with this? Am I missing something about the way the two fingers are supposed to work? Pluck and mute with the same finger? The other thing I was thinking about was the ways you can use this technique to mix things up rythmically. It's a whole new feel, and the space in between notes - even when they're sixteenth notes - changes the sound of the groove hugely. I'd really like to learn how to use this as a tool in my playing, but I'm having trouble working out the technical details. For a while I considered using the third finger to do the muting, which leaves index and middle free to alternate as per usual, but that didn't feel as natural. I'm gonna be working on this one over the weekend with a drum machine, trying to get everything nice and even in terms of note duration and attack with each finger. If someone could help me avoid re-inventing the wheel, I'd appreciate it.
