In the cities, benga, a fusion of Western and Kenyan music, is popular. Benga was originated by the Luo in the 1950s, and incorporates two traditional instruments, the nyatiti, a small stringed instrument, and the orutu, a one-string fiddle, as well as the electric guitar. Taarab music, which is popular along the coast, shows both Arabic and Indian influence. It is sung by women, with drums, acoustic guitar, a small organ, and sometimes a string section accompanying the singers.
