Learning the words to a melody can really help you internalize the rhythm, pitch changes and memorize it well. This helps you connect your mandolin playing to everyone's first instrument - your voice. After learning the basic melody check out a few of the filler licks that will help you a little something extra to those empty measures. Most of the licks aren't too tough. If you need to you can use the difficulty slider on individual measures. After you get this down try out the Bluegrass arrangement!
