Math rock is a style of rock music that emerged in the late 1980s. It is characterised by complex, atypical rhythmic structures, stop/start dynamics and angular, dissonant riffs.

Whereas most rock music uses a basic 4/4 beat (however accented or syncopated), math rock frequently uses odd-time meters such as 7/8, 11/8, or 13/8, or features constantly changing meters based on various groupings of 2 and 3. This rhythmic complexity, seen as "mathematical" in character by many listeners and critics, is what gives the genre its name. Musically, math rock derives from other rock genres, including rock, heavy metal, progressive rock, and punk rock. Math rock often sounds familiar but somehow "off." It fits into those genres but is never a classic example.
