PLENTY of guitar players use the finger-tapping technique to create rapid, fast sounding notes in their solos. RARELY do you ever see or hear someone using more than one finger on their tapping hand.
Joel Hoekstra did a lesson with Guitar World that shows some examples on how to use 2 and 3 fingers on your tapping hand to create some cool sounding patterns.
Joel does a damn good job of muting the strings not being played to get a very clean performance.
Here's the video lesson:
Guitar World was kind enough to provide tablature, and more video, for each of the examples here: http://www.guitarworld.com/columns-rock/your-guide-fretboard-tapping-using-mulitple-fingers/29448
HEY!!! Does Your Rhythm SUCK!?
