What does jazz dance look like today?

Ballet is just like it was before. it is a beautiful and difficult sport. it takes alot of energy, balance, leg muscle, concentration, and persistence. you have to havea love for the sport to do it because if you dont then you wont want to put the work into it. its a sport(like most sports) where you have to put a few quarters in before it can play music. it also takes a lot of talent. More input More modern, more inventive, more expensive. More elaborate with everything. Diets and workouts have improved, too. That's how evolution works. Like all living beings, dance has improved over the centuries.
