It is often inseparable from its literature, music, and mythology. In recent years, there has been an increased interest in fulfilling the need to dance, or to move creatively. This has resulted in increased opportunities for those with background in dance in such areas as health and fitness, dance-exercise, television production, advertising, dance therapy, regional ballet companies, dance ensembles, dance studies and arts schools. The career of a dance performer often flows through the stages of student, dancer, choreographer, teacher. It is usually difficult to tell when one stage stops and another begins.
Students perform, occasionally in the same company as professional dancers.
Performers often teach. Teachers choreograph new dance works for their students. Choreographers are often their own dancers, and dancers are often their own choreographers. One thing common to all dancers at all stages is that all remain students of the dance throughout their careers. Many professional dancers perform in classical ballet, which includes the stylized, traditional repertory, or modern dance, which allows more free movement and self-expression.
