Gumbira took and retrofitted the dynamic and intense ketuk-tilu music. The role of the singer was emphasized to concentrate just on the vocals. He added to it traditional gamelan by expanding the drum section of the ketuk tilu as more of an urban, unique gamelan orchestra from two drums to six. He also sped up the music significantly, increasing the dance role. He also modified the accompanying dance. The modifications retained some of the original sensual moves of ketuk tilu, joining to them a popular martial art called pencak silat. Gumbira called it jaipong. Jaipongan cassettes really feature the singer with their name and alluring cover photos. The singer is given greatest prominence, no longer seen as a prostitute but professional and respectful. This goes with the market demand for solo-superstars.
