How to Forge Aggressive, Memorable Riffs with Unexpected Twists

Whenever I am composing primary riffs for a metal song, one of my goals is to come up with something that not only sounds heavy but also takes the listener on some kind of journey to the unknown!

One effective way to create powerful music is to set up a groove and a riff or sequence, and just when the listener is settled into that groove, something will come along that twists it in an unexpected way.

This is a good example of how to use a chromatic shift to create an unusual and unexpected sound. The first three bars are then restated, and in bar 8 the entire figure wraps up with a chromatically sliding E(b5) shape followed by a bizarre unison bend on the G and B string, as Bb on the G string is bent up one half step to B, sounded along with the open B string. This unison bend from a half-step below adds a “snarl” to the riff that sounds really cool.

FIGURE 3 is a simpler pattern built from a succession of four chords that are sustained over a repeating low-E pedal tone. Each chord is fretted on the A, D and G strings along with the open B and high E. I begin with E5 and then move the shape down two whole steps to C5. The third chord is a very unusual—and great sounding—Fmaj7#11 played against the E bass note, followed by Bb5, filled out with the inclusion of the open B and high E strings.
