In noh, sashi (サシ) is a shōdan.
Sashi is an unmetered text to non-congruent rhythm sung by the shite (or by the shite with shite-tsure), or, in some cases by the waki (or by the waki with waki-tsure). If the sashi is sung by the shite, it is usually the first line. It can also be found after the kuri and before the kuse shōdan in the typical kuri-sashi-kuse sequence.
The content of the sashi varies depending on the play. It can be an explanation of facts, or an internal monologue of a character.
Standard opening lines of a sashi shōdan are sung on a single pitch, with only the last or second to last syllables lengthened and sometimes modulated by fushi. Towards the end of the sashi, the pitch lowers.This melodic contour is used both in the yowagin (soft voice) and tsuyogin (strong voice) modes, and is commonly referred to as sashi-utai. The sashiutai style is not limited to the sashi shōdan, but used elsewhere as well.
