Watch the Carter Style online guitar lesson by Roberto Dalla Vecchia from Solo Flatpicking Handbook
The "Carter Style" consists in playing a simple melody on the lower guitar strings while strumming the higher strings to fill up holes in between melody notes. This technique will allow you to play melody and back up at the same time, all by yourself.
This style was named after Maybelle Carter from Carter Family, a folk band really popular in the States back in the 30’s. The most important element when playing in this style is to strum your chords very lightly, always making sure the melody stands out.
