What Opera; Ballet; or Symphony will be on in November of 2012. I plan on visiting Guanajuato for the month of November this year.
At the beginning of November you're likely to have the opportunity to attend some concerts and dances featuring international artists/performers. That's because the Cervantino Festival will have just ended in Guanajuato. The later you get in the month the opportunities probably minimize.
