What are some similarities between classical ballet and contemporary ballet?

Classical and contemporary ballet bear a resemblance to each other but there are many big differences. Contemporary ballet is usually much faster, and doesn't really tell a story it is usually abstract. There is also much more freedom in contemporary ballet, choreographers can try new and different steps, it also is not as focused on turnout and high extensions, and is alot lower to the ground then classical ballet which is all about turnout high extensions and is very lifted up.
