History and Origin
The exact origin of "What Do I Know" is unclear, but it's believed to have emerged in the early 20th century, possibly as a response to the increasing standardization of sheet music. It's a testament to the oral tradition of music, where performers would often learn and pass down pieces by ear, rather than relying solely on written notation.
