Frederic Chopin 2: The Polonaise
The polonaise is a dance that was fashionable in the Polish court. Since Polish nobility used to like to speak French, the name "polonaise" is French. Eventually, the polonaise caught on all over Europe, and even migrated to America. Lots of operas contain polonaises, and after a while, composers began to use the polonaise as a form for non-dancing, instrumental pieces.
