   The word djent is used to describe the guitar tone made when
a two-octave power chord is palm-muted. Bulb (a.k.a. Misha
Mansoor) says it best: " the onomatopoeia of a heavily palm
muted distorted guitar chord which is usually played as but not
limited to a 4 string double octave powerchord, and as a result
sounds much more metallic and sonically present than a 'chug'
'chugga' or 'djun' per se, and which is basically how Periphery
would describe its palm muted guitar sound.
