There are three pages of finger-picking patterns in my "Carcassi Method for Guitar" book. They use C and G7, and they're only two-to-four measures long (you repeat them endlessly). They start with very simple patterns and develop into some fairly intricate ones. They've all been useful to me, either as just exercises to improve right-hand dexterity, or as actual accompaniment to my songs.


Just my $0.02, fwiw
