Noh

is a major form of classical Japanese dance-drama that has been performed since the 14th century. Developed by Kan'ami and his son Zeami, it is the oldest major theater art that is still regularly performed today. Although the terms Noh and nōgaku are sometimes used interchangeably, nōgaku encompasses both Noh and kyōgen. Traditionally, a full nōgaku program included several Noh plays with comedic kyōgen plays in between; an abbreviated program of two Noh plays with one kyōgen piece has become common today. Optionally, the ritual performance Okina may be presented in the very beginning of nōgaku presentation. Noh is often based on tales from traditional literature with a supernatural being transformed into human form as a hero narrating a story. Noh integrates masks, costumes and various props in a dance-based performance, requiring highly trained actors and musicians. Emotions are primarily conveyed by stylized conventional gestures while the iconic masks represent the roles such as ghosts, women, deities, and demons. Written in late middle Japanese, the text "vividly describes the ordinary people of the twelfth to sixteenth centuries". Having a strong emphasis on tradition rather than innovation, Noh is extremely codified and regulated by the iemoto system. The kanji for 能 means "skill", "craft", or "talent", particularly in the field of performing arts in this context. The word Noh may be used alone or with gaku (楽; entertainment, music) to form the word nōgaku. Noh is a classical tradition that is highly valued by many today. When used alone, Noh refers to the historical genre of theatre that originated from sarugaku in the mid 14th century and continues to be performed today. One of the oldest forerunners of Noh and kyōgen is sangaku, which was introduced to Japan from China in the 8th century. At the time, the term sangaku referred to various types of performance featuring acrobats, song and dance as well as comic sketches. Its subsequent adaptation to Japanese society led to its assimilation of other traditional art forms.
