What is this graceful kind of dance called?

Ballet is a graceful, structured dance style where performers train for years to move with precise control, often balancing on the tips of their toes using pointe shoes, usually accompanied by soft, flowing music.

Hip-hop is a more energetic, freestyle dance style performed to strong beats, without pointe shoes or ballet's formal technique. Tap dance focuses on rhythmic sounds from shoes with metal plates, very different from ballet.

Ballet dancers train from a young age for years before they're strong enough to safely dance on pointe, since balancing on toe tips takes enormous practiced strength.
