What was that Beautiful Music in Wolferl?

All of the music we play in Wolferl truly was written by Mozart, of course. More than six hundred works composed by Mozart in his short life are known today. In choosing music for this program we had in real life exactly the same problem as the two eighteenth-century musicians in our story. There's just so much, and it's all great music. However, none of the things we play in our program was originally scored for one violin and one piano, so we've extracted from and made arrangements of Mozart's works so that the two of us can play them for you. We hope our simple renditions will inspire you to hear the full, original versions of some of Mozart's works.

What are these "K numbers" listed with each composition?
Mozart did not assign opus numbers or other identification to his works, as many later composers did. People often got confused when trying to talk about a specific work. About a hundred years later, in order to solve this big musical problem, LudwigAlois Ferdinand Ritter von Köchel carefully created a catalog of all of Mozarts known works, listed in chronological order. The "K numbers" are the numbers that Köchel assigned to each work in order of composition.
