I had one of the marches from Die Zauberflöte stuck in my head for forever yesterday afternoon – and the really frustrating thing was that it was just a snippet, a few bars, and I could not remember what it was. I knew it was Mozart, but that was all. So I just had to wait until I could connect it to something else that reminded me of where it came from. It’s sort of like the inverted musical version of not being able to think of the precise word you’re looking for.
This is quite possibly the most interesting thing that has happened to me all week.
