 Over time, dansi music changed, partly influenced by the evolution of European and American music.Bands in the 1960s and 1970s typically had electric guitars and electric bass guitars; in the 1980s keyboards became commonplace, and later bands even used synthesizers and drum machines (as was the case with Vijana Jazz).The sound of most recent dansi bands like Gari Kubwa, Tokyo Ngma and Atomic Advantage is actually keyboard-based.
