Hishigi refers to a high, sharp tone of the Noh flute, and includes two types: a “hee”-type kata-hishigi and a “hee-yaa-hee”-type moro-hishigi. The moro-hishigi is typically played at the start of entrance music such as the issei and shidai, or at the end of a Noh performance. The kata-hishigi is played at the start of the haya-fue and kyōgen-shidai, and at the end of certain dances. There are several different kanji used to indicate hishigi.
