Harsh noise rejects melody, rhythm, and harmony in favor of distortion, feedback, and dense static

Harsh noise is an extreme subgenre of noise music defined by the intentional rejection of music theory and traditional song structure: little or no conventional melody, rhythm, or harmony. Artists use effects pedals, synthesizers, manipulated recordings, and custom-built electronics to generate distortion and feedback, producing dense static, electronic screeches, and abrasive sonic bursts. Performances often incorporate improvisation. The style is deliberately inaccessible and lacks commercial appeal — this is not incidental but central to its aesthetic philosophy. Harsh noise primarily circulates in underground contexts, with regional scenes in Japan, England, Canada, Indonesia, and America.

Examples

Merzbow (Masami Akita) is the most cited harsh noise artist: his recordings use feedback loops, processed circuit noise, and distorted electronics to produce walls of abrasive sound with no conventional musical structure.
