Math Rock

A style of progressive and indie rock characterized by complex, atypical rhythmic structures (including irregular stopping and starting), counterpoint, odd time signatures, angular melodies, and extended, often dissonant, chords. It is typified by its rhythmic complexity, seen as mathematical in character by listeners and critics.

While most rock music uses a 4/4 meter (however accented or syncopated), math rock makes use of more non-standard, frequently changing time signatures such as 7/8, 11/8, or 13/8. Drums play a greater role in math rock in providing driving complex rhythms. Math rock guitarists make use of tapping techniques and loop pedals to build on these rhythms. Often, vocals are not overdubbed, and are positioned less prominently. 1998–2006.
