Jaipongan, also known as jaipong, is a musical performance genre of the Sundanese people in the Sundanese language of West Java, Indonesia. Jaipongan includes revived indigenous arts, like gamelan, but it also did not ignore Western music completely despite the ban on rock and roll. It used its sensuality and the sensuality found in a traditional village music and dance, ketuk tilu. However, many believe it is something purely Indonesian or Sundanese in origin and style. It is developed predominately from rural folk forms and traditions as a purely indigenous form. The rise of cassettes and films has led to the popularity of the musical form of jaipongan. It has spread from its home in West Java's Sunda, to greater Java and Indonesia. It can be seen as many regional varieties of gong-chime performance found through much of Indonesia. As also an urban dance form, it is based primarily on the village forms of ketuk tilu and on the Indonesian martial arts, pencak silat. The musical genre is largely influenced from ketuk tilu with traces of the masked theater dance, topeng banjet and the wayang golek puppet theater. Ketuk tilu is its biggest influence, as a traditional Sudanese musical entertainment form.
