Noh chants are made up of numerous shōdan, and ageuta refers to the shōdan or their form. Beginning with higher intervals, the seven- and five-syllable meter verses are sung to a rhythm known as hiranori. While there are fixed forms for the segmenting of verses and the performance of the hayashi, they also change to accommodate irregular vocals. Ageuta are used often and their contents vary. The shōdan of the michiyuki, or “travel song,” and the machi utai are both ageuta.
