His guitar technique makes use of both ringing open strings and dissonant chord voicings, as well as stock power chords in poly-rhythms.

Not including passing notes that create circumstantial consonant harmonies, arpeggiations, broken chords (i.e. a dissonant chord broken into consonant subsets) or inversions.

Typically, in the classical common practice period a dissonant chord (chord with tension) resolves to a consonant chord.

I came up with this dissonant chord that really echoed that sense of frustration.

Preparing tension means to place a series of consonant chords that lead smoothly to the dissonant chord.
