antimusic means opposing music.
Etymology
From anti- + music.
adj
- Opposing music.“In other words, the lack of musical ritual in Canada cannot be understood as yet another case of Muslim antimusic sentiment.”
noun
- Any form of music that defies convention to such a degree that some people would not recognise it as musical.“[…] the current vogue, on the internet, for creating “black midi” files using software to create musical performances with literally millions of notes being played […] is unlikely to appeal to the general listener and we should probably consider it a deviant case of anti-music made for frivolous purposes rather than any kind of polemic.”
