Analysis of Mozart K457 - is asking what key at measure 77 reasonable?

[Teo]

Hi and thanks for the opportunity to ask,

Obviously an examination can ask whatever it wants. Somehow I don't think these questions are correct though:

Of Mozart K457 1st movement which is here:

http://imslp.org/wiki/Piano_Sonata_No.14_in_C_minor,_K.457_(Mozart,_Wolfgang_Amadeus)

The exam asks for the key at measure 75, well C Major? Or dominant of F minor?

The key at measure 77, boy! Mid transition between keys! Bb minor for 2 beats, then E° for 2, but in 2 bars it all goes to F minor.. but to answer what key at measure 77.. I see no measure numbers in the files so I just copied and uploaded this graphic starts at measure 75, the development:


The key at measure 75, C Major is my guess. But Measure 77?!? It seems like all dominant (vii chord) of F minor, but that's looking ahead. Looking just at Measure 77 doesn't give you that, looking ahead to F minor in 79 does.
I'm considering asking for them to review if their questions are actually answerable. Does this sound reasonable?

Thanks for your time
Teo

Yes, Measure 75 is in C Major. I just looked up my (numbered) G. Henle Verlag (Urtext) and this is what I came up with regarding the rest of that section you've provided:

C Major - F Minor - G Minor - at bar 81: back to F Minor, then onto G Minor again.

You need to complain about the lack of detail in the exam question IMO. My experience with Music departments has been DISORGANIZATION and completely irrelevant examination questions eg. Identify all the Chopin Ballades!! Yo, we need to know that - not!!

Good luck!

Hey thanks googols Dirigent! So measure 77, 2 measures after this section starts, with the Bb in the bass, is F minor? Well that's what I think it goes to, but IN THAT BAR.. I'll have to say.. Bb minor! It's a really dumb question.. maybe it's good I don't know who wrote it. But thanks bazillions for the Good luck! It's appreciated! -Teo
