Canned Harmony (1912)

The Professor will not allow his daughter to marry a non-musician, but Billy, her would-be suitor, cannot play a single note. When he is about to give up, Billy’s roommate suggests bluffing his way into the Professor’s favor with the aid of a suitably musical disguise and a well-hidden phonograph player.

Unfortunately the movie Canned Harmony is not yet available on HBO Max.
