奏鸣曲式在舒伯特成熟时期钢琴奏鸣曲中的运用——《a小调奏鸣曲》(Op.42,D 845)第一乐章分析

The application of Sonata style in Schubert's piano Sonata in Mature period :Analysis of the first movement of Sonata in A Minor (Op. 42, D 845)

《a小调奏鸣曲》(Op.42,D 845)是舒伯特钢琴奏鸣曲创作成熟时期的代表作品,也是其生前出版的有限几首钢琴奏鸣曲之一.在第一乐章中,舒伯特紧扣主部主题,通过其各种变体的自然衔接建构呈示部;用变奏技法处理“展开部”,按照和声-调性平衡原则调整再现部调性布局.舒伯特保留了传统古典奏鸣曲式的框架和轮廓却瓦解了其结构基础,从而使该乐章演变为一首幻想性的抒情钢琴小品。

Sonata in A Minor(Op. 42, D 845) is the representative work during the Schubert’s mature period.It is also few piano sonatas published during his lifetime. In the first movement, Schubert follows the theme of the first theme closely and constructs the exposition through the natural cohesion of various variants.The development is treated with variation technique, adjust the tonal layout of the representation according to the harmonic-tonality balance principle. Schubert retained the traditional classical sonata form framework but disintegrated its structural basis, thus making this movement into a lyrical piano fantasy.
