Born in the early 20th century, modern dance is a dance style that focuses on a dancer's own interpretations instead of structured steps, as in traditional ballet dancing. Modern dancers reject the limitations of classical ballet and favor movements derived from the expression of their inner feelings. During the 1900's, European dancers began rebelling against the rigid rules of classical ballet. Turning against the structured techniques, costumes and shoes of ballet, these dancers favored a more relaxed, free style of dancing. Modern dance pioneers often danced in bare feet and revealing costumes. In the United States, several dance pioneers paved the way for American modern dance, including the legendary Martha Graham.
Modern dance encourages dancers to use their emotions and moods to design their own steps and routines. It is not unusual for dancers to invent new steps for their routines, instead of following a structured code of technique, as in ballet.
