Music
There is no such thing as music. Or, rather: there is no such thing as music in the universal, self-evident sense the word implies. The idea that music is a singular human practice — a language we all speak — is itself a culturally specific belief, and a relatively recent Western one. Ethnomusicology has wrangled with this for over a century: indeed, one of the discipline's first moves was to pluralize the term, to insist on musics. Its more provocative assertion, though, was to ask whether the term makes any sense at all in parts of the world distant from the European concert tradition. Many of the world's sonic practices are not thought of as "music" by those who perform them, but instead something more deeply intertwined with ritual, labour, devotion, or speech.
And so, when we say music, we are not naming a universal. In a historical sense, we are naming a (mostly Western) tradition organized around a set of discrete pitches of equal temperament, harmony, the work-concept, the author, etc. The unruliness of "music", then, happens when these particularities begin to masquerade as generalities, especially within technical infrastructures. When a streaming platform categorizes a monsoon raga as "E minor," for example, or a dataset recognizes only key signature and tempo, Western music theory is being mobilized less to describe music than to define it, globally, in epistemologically problematic ways. Music, in this sense, becomes a marker not of what we hear, but of a longstanding process of infrastructural universalization.
