It's not that people find the idea of repetition beautiful. If a melody's pretty enough, you'd want to hear it again in the same work..no?
You don't enjoy the repetition of beautiful phrases? Why is it that so many of the works you work on have that then? XD I recall that you had chopin's op. 72 in e minor. A classical ABA, and you told me you enjoyed it!
As someone who majors in mathematics I find this completely stupid and boring. What's the point of doing this again? In the end its just a sequence of notes...so what?
like someone else said in the comments section, who wants to read a novel of 300 non-repeating words and letters? Rofl.
We were discussing beauty, which is not the same as what pieces I like to listen and play. But I do actually prefer short, compact and forward moving, just say what you have to say and then stop

Repeated or easy to perceive melodies don't make the music more or less beautiful in my ears. And I'd love to play more modern music, but it's just too difficult...
I do not see beauty in words in the way I hear beauty in sounds. That's probably why I hate poetry. To me words are only tools while sounds have value of their own. Does this make any sense to you? So I would not read your book. But I do know people who can enjoy words as themselves.
Now to the video: The method of composing may not make much sense, but the finished product is not ugly in my ears. The combination of sounds contains beauty. You either hear it or not...
