Watch the The Pinky: 3 online guitar lesson by Muriel Anderson from 1-2-3 Fingerstyle Guitar
On the E chord, we'll add the pinky to the 2nd fret, creating an E6 chord. This is a common fingerpickng blues lick. On an F chord, sometimes I'll grab the 1st fret of the 6th string with my left hand thumb.
On a classical guitar with a wide neck, it may be easier to do a bar chord.
