Matthew Bellamy has described the song as: "This stems from hallucinations I had of triangular blades cutting into the back of my head. It's a feeling that information is being infiltrated into your brain. I'd seen a TV programme about psychological warfare and how the government could be controlling us using a type of radiation, sending pulses to our brains. So micro cuts are cuts into your being that you can't see or avoid"

Micro Cuts is a metal song, with art rock, and progressive elements. It is written in D minor, and moves at a very fast tempo of 160 bpm. The time signature frequently shifts between 4/4 and 6/4.

A fan favourite on the 2001 and 2002 tours. The first time Micro Cuts was played live in 2001, it featured different lyrics in place of "Micro waves me insane, A blade cuts in your brain" and the chorus.
