Re the link: my bad! I searched for "serial music Schoenberg" and grabbed the first Google result, without even looking at the title. I did listen to it before posting though, and found it representative of atonal music. It's not that far from Schoenberg, e.g. compare with https://youtu.be/voyLno0HdoA https://youtu.be/voyLno0HdoA (I do like that "echo" effect in the Webern piece though!) Re "abstract music" - how would you call a musical equivalent of abstract art? I think this term conveys the meaning (at least for regular people).
