This melody is very close to the way James Taylor sings it. It sounds simple when you are singing along with it, but the rhythm is quite complex. It has a lot of syncopation and tied notes. The best way to get this down is to listen a lot before playing. Listen to the original recording a lot. Sing a long with it. Use the looper to loop measures. Listen to them repeatedly and hum along. After you can hum or speak the rhythm, playing it will come much easier.
