Fauré isn't doing anything in the least bit outlandish here.
I'm not sure how much i'd consider this as outlandish, to be sure. But i didn't say this was outlandish. I said he does some rather outlandish things in general. I have profound appreciation of Faure, but wouldn't be able to make strong statements about his tendencies other than they are complex and often without precedent.
A difference in statement and perceived statement enough to deserve being corrected. The passage in question does have a very fairly unusual modulation back to C. The circle of fifths sets up momentum and expectation since it is a sequence which is sort of upset by the D.
I don't think he's breaking any rule either, but most of us expect a circle of fifths to do what it usually does. Hence the confusion of the OP.
Thanks guys for clearing this up for me!
great music btw:
Yup, happy to help. It is very nice indeed. I remember accompanying this in a viola arrangement, a Slovak girl i was seeing at the time in high school was playig it for an exam. Life is so weird.....
