Pythagorean system was not arbitrarily based on ratios. It was intentional and was derived from a very close study of properties of various sound objects (string, bell, hammer etc).

it's quite the opposite. It is the sound and music that comes first, which can in turn be explained and represented mathematically. And, we cannot, yet, determine, through mathematics or other sciences what is 'musical'. But experience and:

It is mostly a matter of ever evolving taste. 14th-15th century has seen some pretty advanced species counterpoint and the third was rather considered as 'weak' consonance. You're talking about circa 6th-11th century. but then again, things moved very slowly then and there was a lot of overlap between different 'new' developments.

I think that math was used mostly to help understand certain aspects of music. And, sorry, I don't recall anyone trying to teach me sonata form in mathematical terms. Could you point me to some resources? I'd be interested to know more...

I'm not sure about 'very experienced' listeners. You mean music students, composers and such? A very experienced listener will simply follow the harmonic progression and will 'know' that it does not finish on the 'right' key even if it 'feels' otherwise.
BTW, i don't think that music is a result of some applied mathematics. But many things can be explained using simple arithmetics.
