Noise music: expanding the definition of musical sound

Noise music sits at the edge of what most listeners accept as music at all — which is precisely why its history matters for anyone navigating experimental and electronic lineages. Understanding noise means learning to argue a case: that feedback squall, circuit-bent toy keyboards, and sustained walls of static are compositional choices rooted in a coherent intellectual tradition, not accidents or provocations for their own sake.

The capstone asks for exactly that argument in essay form — a traced lineage from manifesto to contemporary genre. Getting there requires building conceptual scaffolding before the timeline.

The first scaffold is definitional. Before placing noise historically, a learner needs to hold Sangild’s threefold distinction (acoustic spectral noise vs. communicative interference vs. subjective discomfort) steady in working memory — it is the conceptual vocabulary the whole essay depends on. This is an automaticity-critical fact that rewards early drill. Alongside it, the core principle that the boundary of legitimate musical sound is historically contingent (the expanding-definition atom) gives the essay its spine: each successive practice annexed further ‘non-musical’ sound into composition, so the essay’s argument is ultimately about that moving boundary, not a fixed sonic category.

With that vocabulary in place, the historical arc opens naturally. Russolo’s 1913 intonarumori manifesto provides the origin point — specific enough to cite with dates and reception. Cage then supplies the philosophical lever: his all-sound principle dissolves the musical/non-musical distinction entirely, enabling every subsequent practice. The capstone essay traces this arc explicitly, so both atoms are non-negotiable gates.

The middle section of the essay covers the genre map: harsh noise as a principled rejection of melody and harmony; power electronics as the moment cheap synthesizers opened noise to non-musicians; and the Japanoise scene (Merzbow, Hijokaidan, Hanatarash) as the crucible where the genre cohered in the 1980s Kansai underground. Harsh noise wall extends this into radical stasis — Vomir’s “no ideas, no change, no development” — which is theoretically illuminating for the essay’s argument about legitimacy.

The final required section grounds the compositional tools the capstone explicitly names: feedback as a performance instrument (room acoustics and signal chain as score), circuit-bending as a DIY democratisation of noise creation, and extreme frequency ranges as a deliberate exposure of playback-system limits. Each maps directly to a capstone sentence.

Supporting atoms enrich without gating: deeper Merzbow scholarship, the Kansai–New York no wave genealogy, post-noise’s ambient turn, and Attali’s pre-figurative theory all reward further reading once the core essay is drafted.
