Watch the Frailing online guitar lesson by Muriel Anderson from 50 Right-Hand Techniques You Must Know
Many people asked me about how to do the frailing on the guitar in my bluegrass medley / Angelina Baker. I teach this tune in its entirety on my Innovations DVD.
Hold your right hand stiffly in the shape of a claw and hammer nearly straight down with the wrist (hence the term claw-hammer). Doing so, strike the 2nd string with the back of the fingernail of the middle finger. The fingernail will end up resting on the first string. Repeat the motion, the second time softer in volume.
The first down stroke is hit hard, and on the second down stroke the hand bounces not as high; like the second bounce after you drop a ball.
The frailing technique I do on the guitar differs from the banjo in that the thumb plays the high 5th string on the banjo, but since that's a low string on the guitar I hook the first string either with my ring or index finger on the way up after the second down stroke, to imitate the sound of the 5th string on the banjo.
