Tchaikovsky's ballets are popular favorites. He created many fascinating dances...sugarplums, snowflakes, swans, and mice to name but a few. Did you know he had dancing cats?
The Royal Opera House Ballet has a number of dances on their website, including the White Cat and Puss-in-Boots from Tchaikovsky's Sleeping Beauty.
