Watch the Rockin' Hybrid Rhythm online guitar lesson by Walter Broes from Rock, Billy, & Boogie Guidebook
Using a hybrid grip where you play with a flatpick and your fingers can be a great way to spice up your rhythm playing. There’s more going on than you can typically do with just a flatpick, and having the flatpick ready to go at any time leaves you the possibility of throwing in a lead fill or faster eighth-note or triplets.
Listen to the work of the great James Burton for numerous examples of this in a rockabilly or country context. Laying back on your right hand a little can work wonders for dynamics in this style, just keep your basic neutral attack fairly light, making it much easier to emphasize certain phrases by giving you “an extra gear” volume-wise.
