I answered a question that was shortly afterward closed, correctly, as a duplicate. I put significant time and effort into developing the answer, so I'd hate for it to be lost because of its question's current "duplicate" status. I also believe it includes a perspective and information not currently addressed in the "canonical" question.
Is it considered bad form to copy my answer to the canonical question? If I do copy it, should I delete the one associated with the now-duplicate question? Do answers get "lost" because they exist in duplicates of other questions? Should the two questions be merged?
The question in question: What's the Reason for Naming Major Second a Diminished Third?
