This dancer is performing a jazz dance.  Jazz has many types of steps.  First, to perform jazz, you must have jazz shoes.  Like the ones in the picture.  Jazz can be any type of moves you want.  Unlike ballet where you have to be graceful, and tap you have to be very up-beat.  Jazz is a fun type of dance.

This paragraph is about ballet.  Some of the Basic steps to ballet is the 5 positions, also you must learn the entire bar routine. There are two types of ballet.  There is just regular ballet and a very hard type of ballet called Pointe.  The dancer in the picture next to me is performing Pointe.  It is called Pointe because you must perform it on the "point" of your feet.   

This is a picture of dancers  doing a tap dance.  Tap dance is a series of steps.  A lot of people call it rythmic dancing.  Tap dancing in early history included challenges and stealing steps.  After the twenith century tap really grow and expanded.  It was included in films and Broadway plays.
