This months lick uses all natural harmonics to create a cool harp like effect. Natural harmonics are created when you slightly braze a note with the tip of your fretting fingers, normally with your first and second, but you can use any fingers you like.
A good example is Van Halen's Panama where Eddie Van Halen uses Natural harmonics throughout the song. Included is the Sheetmusic, Tab and Midi File for easy reference. See the attachments below.
