A good way to do this is to use seventh chords, which are rarely heard in metal. This month, I'd like to demonstrate a few cool ways one can use one particularly cool- and tense-sounding seventh chord in heavy, thrash-style riffs. Of the different types of seventh chords—major-seven, dominant-seven, minor-seven and what have you—the one that appeals to me most is minor-seven-flat-five (m7b5), also known as half-diminished-seven.
