The Vistula is a famous river that flows across Poland. Here is a recording of a polonaise that I wrote called “Moonlight on the Vistula.” I hope that you enjoy listening to it. If you like this music and would like to play it yourself (or know someone else who might like to play it), you can purchase the sheet music at this link:
