Modern Dance is a style of dance that was born in defiance of structured or traditional dance (like ballet for example). This defiance of structure or traditional dance steps makes Modern Dance difficult to define. A dancer's style can cover a wide scope of moves influenced by many other dance styles. However there are discernible characteristics of Modern Dance. For example, in Ballet dancers are meant to appear 'light' and 'weightless', while in Modern Dance dancers are encouraged to use gravity and their bodies to convey 'feelings' and emotions. This characteristic helps to define Modern Dance, that is that a dancer is encouraged to be expressive of their inner feelings and emotions. A dance can be interpretive in that regard, and it can be improvisational versus a traditional choreographed dance.
