• Structure: 歌劇 (かげき) is a noun for a staged dramatic work whose story is carried through singing and orchestral music.
• Basic usage: 本格的な歌劇を鑑賞する makes the theater work the object watched, while この歌劇では合唱が役割を担う sets one production as the scope in which the chorus has a role.

  • 歌劇を鑑賞する concerns the complete work, while 歌劇では合唱が explains a chorus function within it. One choral number should not be equated with the whole opera.
