Ms. Yeh replied that "Fugue" was created by Bach. The posterity set this creative format and musical theories based on a large amount of his works. The structural difficulty of fugue lied in the fact that stretto should be harmonious in different voices overlap. Therefore, careful calculation must be set in syllabic fashion.

报告人回答，「复格曲」是由巴赫所建立，后世是根据其大量的作品标定此一创作形式及音乐理论；而复格曲的结构难度在於叠句部分必须为和谐的音层，因此在音节设计上得仔细斟酌。
