This appears to be a mediocre piece of undergrad "research", which is to say, the theoretical material is entirely plagiarized without citation. Even the applied analysis (Beethoven's 9th, 2nd mvt. mm. 143-172) is directly lifted from another work. The application of group-theoretical ideas to music theory (in particular, the rules underpinning voice leading) is quite interesting, however! People have been interested in the link between symmetry and musical beauty since the time of the Pythagoreans. Looking through the modern lens of group theory shows a delightful simplicity: if you look at the world of musical operations in this way, the ones that sound best are often small deviations away from maximum symmetry. There are far better places to start, if you're interested, covering much of the same (plagiarized!) material: https://www.math.drexel.edu/~dp399/musicmath/algebraicmusictheory.html https://www.math.drexel.edu/~dp399/musicmath/algebraicmusict... https://sites.math.washington.edu/~morrow/336_09/papers/Ada.pdf https://sites.math.washington.edu/~morrow/336_09/papers/Ada.... https://alpof.wordpress.com/category/music/math-music/neo-riemannian-theory/ https://alpof.wordpress.com/category/music/math-music/neo-ri... http://www-personal.umd.umich.edu/~tmfiore/1/mathmusiccolloquiumslides.pdf http://www-personal.umd.umich.edu/~tmfiore/1/mathmusiccolloq... https://www.maa.org/sites/default/files/pdf/upload_library/22/Hasse/Crans2011.pdf https://www.maa.org/sites/default/files/pdf/upload_library/2... Or, of course, follow the citation chains on Wikipedia: https://en.wikipedia.org/wiki/Neo-Riemannian_theory https://en.wikipedia.org/wiki/Neo-Riemannian_theory https://en.wikipedia.org/wiki/Transformational_theory https://en.wikipedia.org/wiki/Transformational_theory

I know you've been in the music business for a few hundred years, Josquin, but there's no need to be so harsh about this undergrad poster! From what I could figure, it's something like a final project for a class on Mathematics and Music at UW Eau Claire. The background material on transformations of sets of pitch classes is in the course textbook. (This doesn't take away from all the citations you helpfully provided, though.)

  If it's an undergrad project, it absolutely should cite properly; so that is at least worth pointing out. To be fair though, posters are often a bit sloppy this way, and in context supposed to be supported other ways.

    It's a one page summary with pictures rather than a research paper or such like. There's quite likely some article with sources elsewhere.

      It's a scientific poster layout, very standard. They typically have some citation, but only major ones.

I'm trying to decide if I should go down this rabbit hole. The math looks easy enough, but I know nothing about music. Nothing. And I'd love to learn, of course, but I can see myself buying a keyboard and plinking out some of these transformations and that seems like a long time to go without a payoff. What's your musical background?

  You may be interested in the twelve tone you tube channel, fwiw - particularly the earlier ones where he discusses the fundamentals.

  I've been down this rabbit hole for a few years, except making procedural music with code rather than physically playing an instrument. No musical background at all (I started by googling "chord" etc). My take is, the basics - the math behind chords and chord changes, summarized on the left page of the PDF - are embarrassingly simple; you can know everything there seems to be to know in a weekend or two. However for the application - using those basics to create or understand music - I'm still not entirely sure there's anything to know. That is, one can find scads of sources online similar to the right-hand page of the PDF, which analyze the structure of some phrase or composition. But it all seems to pretty much boil down to giving names to things; there don't seem to be any generally applicable principles. The closest thing we have seems to be voice leading rules, but they're very much "doing X sounds good except when it doesn't" sorts of things.
