Watch the Harmonic Soul online guitar lesson by Chris Buono from 50 Metal Guitar Licks You MUST Know
Natural harmonics can play a key role in shaping completely cool sounding metal riffs. Just check out Dave Mustaine's take on this idea during the intro riff to "Tornado of Souls" from Megadeth's Rust In Peace album where choice 7th fret harmonics are played along side a crushing 7th position B5. Both the differing timbres of fretted notes vs. harmonics and the unexpected intervallic leaps make integrating harmonics of any type into your riff writing a must if you're searching for another creative avenue. Check out this must-know take of Mustaine's riff and then try constructing your own.
