This application allows users to become composers themselves in a playful way. Under Marschner's guidance, they can create their own composition based on Marschner's "Der Vampyr" using a range of instruments such as violin, viola and cello.

Opernplatz is probably one of the most iconic places in Hanover. Even though everyone knows the square and the opera house, the statue of Heinrich Marschner at the edge of the square doesn’t get much attention. Marschner was a Romantic-era composer who wrote 13 operas. Today, the composer has largely been forgotten. For many, this is undeserved, as he had a direct influence on greats like Richard Wagner with works such as "Der Vampyr."
