An interesting effect to incorporate into a Metal guitar lick or solo is a harmonic. A harmonic is a bell-like sound that is produced by lightly touching the string directly above the fretwire, then picking the string. The string is not pressed against the fretboard.
The easiest harmonics to play are natural harmonics, found at the 5th, 7th and 12th frets. This technique will require a great deal of practice to execute cleanly.
Harmonics are notated on the tab with a dot and the wording har… below the tab.
Harmonics can be played on all six strings and two or more harmonics can be played simultaneously.
This lick combines a power chord rhythm pattern and harmonics.
