We measured the predictability of tone sequences in music by Arnold Schoenberg and Anton Webern and found the successive pitches were less predictable than random tone sequences.
How can something be less predictable than random? Doesn't random imply something which cannot be predicted?
In atonal music, it just sounds like a bunch of random pitches, though in reality everything is very sensible ... on paper.
