Really lovely idea and brilliant execution. For people who don't get the reference, one of the defining pieces of the Minimalist movement in 20th century music[1] was "In C" by Terry Riley[2]. Minimalist pieces often (but don't always) include elements of non-determinsm like in this. [1] Minimalism here doesn't mean "not many notes" it means deliberately restricting the range of harmonic and rhythmic materials availa…
This is not necessarily what minimalism means. Minimalism is just an abstraction for certain kinds of art, possibly with various incompatible techniques. For some artists (not just musicians, but also painters, poets etc) minimalism means "repetition"-ism i.e. art with excessive amount of repetition to the point that you'd normally expect it to be "boring" but it somehow uses it to its favor with rhythmic, harmonic, or formal techniques. Philip Glass is the pioneer of this idea in music, and I personally consider him one of the most creative and groundbreaking artists ever lived. His music is very tonal, "simple" and repetitive in his oeuvre (i.e. repetition not just in one work, but repetition among his body of works like minimalist painters Mondrian and Rothko) which makes him a very very controversial musician, some critics considering him a charlatan. To me, he's a Schoenbergian figure who is making a bombastic and over-the-top artistic statement by going against the current of his artistic tradition while remaining firmly in it. Similarly, Schoenberg was also considered a charlatan during his life, especially early on.

Oh also if you ever think "classical music doesn't have a cultural force anymore" please pay attention to contemporary film music that's not neo-romanticist. You'll see that there is tons of minimalist influence from Glass, Reich, Andriessen, Richter etc...
