Quick question: When I am looking to use a pivot chord to modulate between two keys where the pivot chord is common to both (or where there is a chromatic mediant relationship Btw the roots of the chords) is it only "correct" for me to use this modulate btw the closely related keys or is it kosher to use these relationship to bridge keys that are more distantly relative to each other. For instance, in order to moduate From A major to say C Major.

I just realised the stupidity inherant to my questionstion insofar as there happens to exist no common chords between Cmajor and A Major by which to pivot. hehehe

not seeing the forest for the trees I guess...Panickedly trying to find my hat only the find that in the mean time, it has been sitting on my head (-:

Can anyone think of any examples of non closely related keys wherein there exists a common chord (excluding of course, all enharmonic respellings of fully diminished 7th chords).
