Jazz is about rhythm, technique and improvisation. A big part of the dance involves the dancer’s expression and attitude. Similar to how ballet relies on classical music, jazz dance relies on jazz music to drive the dance. Jazz remains one of the most dynamic dances in American dance as it combines various dances such as tap, ballet and African-American dance.
Familiarize yourself with jazz dance music. The musical "Chicago" features popular jazz dance music such as "Hot Honey Rag" and "All That Jazz." Jazz dance music is mostly early-20th century jazz. Before you begin to dance with the music, you have to become familiar with it and absorb the beats, downbeats and melody. A huge part of jazz dance is about interpretation, so your body needs to be attuned with the music before you can start interpreting it with dance techniques.
