We need more sweet tone (prefer fretboard) and more elastic rhythm: this is not a dance, we have to imitate the human voice when sing this beautiful melody. Every repetition is a good opportunity to variate a little bit or more..
"It's easy to play any musical instrument: all you have to do is touch the right key at the right time and the instrument will play itself" (J. S. Bach)
..You know, the guitar is a very special instrument! (D. Lazzari)
