Mishearing as a creative act lays out the case for misinterpretations of other people’s words/lyrics/statements as potential sparks for new creative works. I’ve several poems in progress like that: I knew my wife said, “You can’t lead where you haven’t gone.” and that I heard, “You can’t leave where you haven’t gone.”
This can also happened with things misread or mis-seen. A T-shirt that said “Prefect Circle” with a fold in the middle mis-read as “Perfect Circe”. I’m not sure what a Perfect Circe is, but I’m working on it.
