Watch the Coordination Nation online guitar lesson by Peppino D'Agostino from Acoustic Poetica: Fingerstyle Etudes
This exercise is designed to improve the coordination of both hands working together. Make sure to use the right and left hand fingering indicated in the standard notation even if it seems difficult or awkward at first. Let the bass notes ring throughout the measures and sustain them as long as possible. Use your thumb to strike the 6th, 5th, and 4th string, your index finger to strike the 3rd string, the middle finger to strike the 2nd string, and the ring finger to strike the 1st string.
