Ketuk tilu was a musical genre based on ritual and celebration in the villages of the Sundanese people, meaning three kettle gongs. It was known for complex drumming coordinated with equally dynamic solo female dancers. The music was performed for planting and harvesting rituals and later celebrated village life, circumcision and marriage, expressed fertility, and displayed sensuality, eroticism and even sometimes “socially accepted prostitution.” Ketuk tilu was very popular in the Sundanese villages, but the urban Sundanese considered it unrefined and inappropriate because the music involved males and females dancing together suggestively, or mixed dancing between men and ronggeng, or prostitutes. Ronggeng probably has existed in Java since ancient time, the bas reliefs in Karmawibhanga section on Borobudur displays the scene of travelling entertainment troupe with musicians and female dancers.
