*''Tsure'' (lit. "accompanying") - divided into ''wakitsure'' and ''shite-tsure'', the ''tsure'' actors play figures accompanying the main roles. In many plays where the ''waki'' is a wandering monk, for example, the ''tsure'' play other monks accompanying him.

*Chorus (J: ''jiutai'') - Noh features a chorus of six to ten people, usually eight, visible and seated onstage at stage left, facing towards stage right. The chorus generally chants narration, as well as often chanting lines for the characters. Members of the chorus are typically ''shite'' actors themselves, though originally (in Zeami's time) it was ''waki'' actors who composed the chorus.<ref>Quinn, ''Developing Zeami'', 132.</ref>

*''Hayashi'' - in Noh, the musicians, known as the ''hayashi'', sit along the rear wall, facing the audience. They play a variety of instruments, chiefly flute (''[[nokan|nôkan]]'') and several types of drums (''[[kotsuzumi]]'', ''[[otsuzumi|ôtsuzumi]]'', and ''[[shimedaiko]]''). Unlike in the [[Edo period]] theater forms of [[kabuki]] and [[ningyo joruri|ningyô jôruri]], Noh does not incorporate [[shamisen]] or other string instruments.

As in other theatrical forms, the musical instruments are frequently used to suggest sounds which help to set a scene, such as gentle or harsh winds, rain or snow, waves, or forest sounds such as the snapping of twigs.

*''Kôken'', or "stage assistants," handle a variety of tasks including helping adjust actors' robes, handling props, and assisting in onstage costume changes. Insofar as they are not characters present in the world (setting/plot) of the play, they are meant to be ignored by the audience, though they make little overt effort to hide themselves.
