Lesson 7: Slapping Part 2:
Thumb Slap, Left Hand Slap, Hammer-On
This is another very important technique for slapping- the thumb slap and the left hand slap. The thumb slap technique stays the same as the previous lesson, but this time the left hand (right hand for left handed players) is going to hit all the strings with four fingers flat, in order to create a percussive sound, not a note. Start practicing the first exercise, as if you were practicing drums. Usually drummers are very good at these exercises. If you're stuck in traffic you can practice these exercises on your steering wheel!
