Noh, or Nogaku—derived from the Sino-Japanese word for "skill" or "talent"—is a major form of classical Japanese musical drama that has been performed since the 14th century. While the field of Noh performance is extremely codified, and regulated by the iemoto system, with an emphasis on tradition rather than innovation, some performers do compose new plays or revive historical ones that are not a part of the standard repertoire.
