The late Christopher Longuet-Higgins invented a musical shoe, which could tap along to arbitrary pieces of music that were played to it.
I wonder how easy it would be to write a tool that took music and rendered it into a sayable form like in the title of this post. It might tell us something about musical perception. I can’t see any practical uses. Unless you’re a novelist.
According to one question-answering site, though, there is great need of something that runs in the opposite direction, a sort of text-only Shazam: Whats that Beethoven song? [sic]
