I'm going to show you another technique that's very useful, from the classical genre. It's called the tremolo. Now, tremolo is designed to have a busy single note happening while you play kind of melody notes on your bass strings. I'll show you. The pattern is thumb first, the A finger, M finger, I finger. But, your M finger and I finger, and your A finger, are staying on one string while your thumb moves around on the bass string. So, [playing guitar] like that. And then, once it's sped up, you can do things like this. [playing guitar] That's a very classical technique. Very easy way to come up with some new, interesting sounds that maybe you never thought of before, that you can borrow from the classical world.
