This is a wonderful arrangement of this classic tune. Chord melody uses chord movements that coincide with changes in the melody. It creates a full and beautiful sound. It's also great practice for working on chord changes and your knowledge of chord shapes and inversions. The Melody falls mostly on the 1st string. Since it is the highest pitch in most of the chords, it should jump out to the listener as long as you aren't too heavy handed in picking the other strings in the chords.
