Watch the Brush Up online guitar lesson by John Hatcher from Fingerstyle Blues Roots

Brush-ups are a rhythm technique that emulate strumming sounds of using a flat pick. Use your index finger to pull through the strings with an upstroke. This produces a fluid strumming sound that you just can't get with a plucking technique. You can hear this technique in action in the guitar break of "Love in Vain" by Robert Johnson.

In this lesson, I'll demonstrate the cool sounds that you can get using the brush up technique.
