It is more about the standard you are playing to. You will encounter various degrees of competitiveness depending On the school and program. To consider are you for bach mus music in performance? A bach of education ? A bach of arts in perdance? You are looking to show the panel you have the potential to successfully handle the load of their program so competence and musical creativity. I believe for an audition the Waldstein and to eat sonatas could be a biting for undergrad. Might be better to stick with less difficult standards and really play them exceedingly well. I would move towards early Beethoven were it me and I had to do Beethoven ( I successfully auditioned with Mozart)
Impressionistic/20th Century suggestions:
The twentieth century seems to have ended rather early (1905, 1901, 1908 and 1917). Are you related to the Romanovs?
the century did not end but musical time stood still. There was no music composition after 1920. Nothing. Not a single note. And composers just vanished mysteriously just like some dinosaurs or the Inca. It's true. Just read the audition an competition requirements for modern music selections. I read this in the internetz so I know thi to be certain .
That explains everything except several shelves of my music collection.
i'm very interested in those four fugues (that do not exist of course)
