Technical avises - Picks harmonics
Hold your pick so that your inch and your right index
rub slightly on the string when you make the notes.
This will produce harmonics in addition to the note
carried out. This technical is often use to highlight
one or more notes in your leads or rythmic guitar. Randy
Rhoads, Eddie Van Halen, Vito Bratto and several other
guitarists use this technique in the rock.
I recorded below two examples of his use:
