Watch the Arpeggios: 2 online guitar lesson by Muriel Anderson from 1-2-3 Fingerstyle Guitar

A variation to the standard arpeggio has the treble strings played in the opposite order, 1st, 2nd, 3rd, instead of 3rd, 2nd, 1st. Banjo players refer to this as a "backwards roll" and use it mixed in with other patterns.

Getting used to different patterns and making variations within each song brings more variety to your accompaniments.
