Here is a basic lesson in whole note study. Make sure that you are using the appropriate finger for each note. Say the notes out loud as you play them

E F G A B C D E F G A B C C B A G F E D C B A G F E

Take your time, go slow at first and don't forget to alternate fingers on your right hand. Tip: write the notes underneath the TAB so that you can look at both at the same time.
