Taiko [SEP] Kumi-daiko
In addition to the instruments, the term "taiko" also refers to the performance itself, and commonly to one style called "kumi-daiko", or ensemble-style playing (as opposed to festival performances, rituals, or theatrical use of the drums). "Kumi-daiko" was developed by Daihachi Oguchi in 1951. He is considered a master performer and helped transform taiko performance from its roots in traditional settings in festivals and shrines. Oguchi was trained as a jazz musician in Nagano, and at one point, a relative gave him an old piece of written taiko music. Unable to read the traditional and esoteric notation, Oguchi found help to transcribe the piece, and on his own added rhythms and transformed the work to accommodate multiple taiko players on different-sized instruments.
