OK, we're back to a second verse, however this time Marco takes the vocal approach one step further by playing this section entirely with tapped harmonics with the right hand. Using this technique gives an even more exaggerated singing quality if the harmonics are cleanly produced.
The best results are achieved by using a very light, bouncing kind of movement with the right hand. Be sure not to leave your right hand finger anywhere near the string as this will tend to muffle the notes and prevent them from ringing clearly.
Only careful practice will allow you to achieve this in the desired manner, so approach this section with sensitivity.
