This purpose of this study is to analyze Wagner's 1832 work "Piano Sonata in A Major" to discuss the music development in the Romantic period (1820-1900), the rise of humanism and the historical positioning of the piano sonata. It is different from the classical period in which the praise of "God" is the main focus, but "people" is the main focus. Therefore, many traditional classical composition styles and understandings and cognitions of music have been broken, and many songs different from the classical period have been created. Various art forms, such as: Music drama, Symphonic Poem , Romantic Opera , etc. Wagner's works broke the framework of the existing music forms at that time and created conflicts. And the unique style of opposition, not only the frequent use of Chromaticism, non-chord tone, suspension, etc. in harmony, but also enriches the sound of music orchestration and texture , strengthened the integrity and uniqueness of each part on a large scale, and we can not only find the above-mentioned characteristics and styles from Wagner's opera works, but also get a glimpse of Wagner's writing style from piano sonatas With chord configuration, "Piano Sonata in A Major" has many similarities with many writing methods in Wagner's symphony. , Actual performances support Wagner's music style, and put forward well-founded performances and interpretations.
