路德维希·凡·贝多芬是德国杰出的钢琴家、音乐家,他的钢琴奏鸣曲最能代表其艺术成就,被称之为“新约全书”。尤其是他晚期所创作的最后三首钢琴奏鸣曲(Op109、Op110、Op111),充满了幻想性和抒情性,倾向于浪漫主义音乐特色,将他的创作推向了艺术的巅峰。本文以贝多芬晚期最后三首钢琴奏鸣曲为例,对其晚期钢琴奏鸣曲的演奏要点进行了深入分析,希望能够开辟有关贝多芬钢琴奏鸣曲研究和演奏的新视角。 Ludwig van Beethoven, an outstanding pianist and musician in Germany, whose piano sonata best represents his artistic accomplishments, is called the New Testament. In particular, his last three piano sonatas (Op109, Op110, Op111) were full of fantasy and lyricism. They tended to be romantic music and pushed his creation to the pinnacle of art. In this paper, the last three Beethoven pianos in the late Sonata as an example, the key points of the late piano sonata are analyzed in depth, hoping to open up a new perspective on the study and performance of the Beethoven Piano Sonata.
