奏鸣曲式的起源、发展和定型虽在音乐史的研究中已有明确的结论,但中间的过渡形态和阶段还研究得不很充分。文章希望通过对C.P.E.巴赫奏鸣曲结构的分析研究,来厘清这一脉络的发展线索,以及其作为奏鸣曲式奠基人所起的具体作用。 Although the origins, development and stereotypes of sonata have been clearly defined in the study of the history of music, the transitional forms and stages in the middle have not yet been fully studied. The article hopes to clarify the clues of the development of this context by analyzing and researching the structure of C.P.E. Bach Sonata and its specific role as the founders of Sonata.
