n.
1. A term that encompasses most all modern
progressive rock or metal that places emphasis on time signature modulation and meter as opposed to dynamics, melody, or harmony. "Math rock/metal" encompasses everything from the jazzier leanings of post rock act Slint, to the phrase swapping and odd meters of
the Dillinger Escape Plan, and even the hemiola and polyrhythm experiments of bands like Meshuggah and Tool.
2. A term often falsely described as "intelligent music" by people who simply
regurgitate what they are told and apparently have no idea how to count.
