Each measure in "Prelude in C Minor" is a great micro exercise by itself, developing strong alternate picking and finger dexterity. Don't forget to use strict alternate picking beginning with an up stroke for this example. Learn one measure at a time, then begin to connect two measures while keeping a steady tempo. Continue adding measures until the end. Tunes like this one help us to develop a longer attention span and laser beam focus.
