Glitch is an experimental electronic music style built from the deliberate use of digital errors — clicks, pops, CD skips, sample-rate artifacts — as compositional elements. The genre emerged in the late 1990s through artists like Oval, Autechre, and Pole, and consolidated on labels like Mille Plateaux, Raster-Noton, and 12k. Tempos vary widely; many tracks are beatless or loosely metric. Glitch overlaps heavily with IDM (intelligent dance music) and ambient, and is more aligned with art-music traditions than with club programming. The style has influenced contemporary experimental electronic production across genres — from Oneohtrix Point Never's deconstructed pop to the textural side of contemporary dubstep — and remains a touchstone for producers prioritising sound design over groove.
