About: Okuda Hiroko

Okuda Hiroko (奥田 広子) is the Japanese inventor and musicologist who, at the start of her career in 1980, composed the rhythm and bass preset backing tracks included in Casio's electronic keyboards. These included the "rock" rhythm, which became the ubiquitous Sleng Teng Riddim, heralded the Ragga movement, and has since underpinned hundreds of hit reggae songs. Okuda and Casio have allowed her backing-rhythm work to proliferate under a free attribution-only license, which have contributed to their popularity and widespread use. She holds more than a dozen patents in the fields of electronic musical instruments and presently works at the intersection of electronic music and visual art.
