Currently reading Harper's Infinite Music where he describes music as an activity (doing-music o "musicking", a term borrowed from Small) in an infinite music space and I think it resembles the wittgensteinian notion of language. Language is, according to Wittgenstein, a wide range of activities (language games) established in a form of life. Harper describes "alien genres" as entirely new ways of practicing music, "they recognise the mutually supportive relationship between music and everything we do in our lives" and one example that he makes is a game where doing-music becomes collective and interactive with our surroundings. Moverover, Wittgenstein often compares language with music when it comes to the notion of understanding: "Understanding a sentence is much more akin to understanding a musical theme than one may think".
