A tricky question about a movie?

In the horror film "The other side of the door" (Netflix ca 43 min), the girl plays a piece on the piano where the ghost of her brother continues to play. Unfortunately, Shazam can't grasp that, so I'm here to you vllt someone knows the piece and can help me with it.

It should be there.
