Hatsune Miku
Hatsune Miku was the first Vocaloid developed by Crypton Future Media after they handled the release of the Yamaha vocal Meiko and Kaito. The name of "Hatsune Miku" was conceived soon after the Vocaloid 2 announcements, when an English and Japanese vocal were developed for the character. The intended design was delayed and later used for Megurine Luka instead. Miku was intended to be the first of a series of Vocaloids called the ""Character Vocal Series"", which included Kagamine Rin/Len and Megurine Luka. Each had a particular concept and vocal direction.
Minoru Miki
Miki was born in Tokushima in 1930, and his first musical experiences were connected with the traditional music of his region. He had no formal music education before he moved to Okayama for high school, where he first contacted with European classical music. From there he moved to Tokyo, graduating from Tokyo University of the Arts in 1964.
Immediately in that year Miki founded Pro musica Nipponia (日本音楽集団), an orchestra of traditional Japanese instruments for which he would compose a large number of works. He also began cooperation with koto virtuoso Keiko Nosaka, developing the 20-string koto and reviving the instrument's repertoire with many new works in a variety of genres and combinations, including five concertos for koto and orchestra.
Miki composed his first opera, "Shunkinsho" (based on Tanizaki's eponymous novel), in 1975. Interest by members of the English Music Theatre Company in Japanese traditional music led to contacts with Miki which resulted in the commission of the opera "Ada, An Actor's Revenge", to an English libretto by James Kirkup. "Ada" premiered in London in 1979 and was one of the last works commissioned and performed by the EMTC before its ultimate dismemberment in 1980. During this period Miki developed a relationship with director Colin Graham that was to last until the latter's death in 2007. The most notable result of this cooperation was the opera "Jōruri", commissioned by Graham for the Opera Theatre of Saint Louis (where he had moved following the disbandment of the EMTC) and premiered there in 1985.
