The basic music form structure has the three-step structure which consists of maeuta (the former song), tegoto (Japanese Koto) and atouta (the latter song), but in large scale songs, many have a structure which consists of maeuta, tegoto, nakauta (the middle song), tegoto and atouta.
基本的な楽式構造は、前唄-手事-後唄という三段構成をとるが、大曲になると前唄-手事-中唄-手事-後唄という構成のものも多い。
