Sergey Sergeyevich Prokofiev's (1891-1953) piano sonatas hold a significant place within the vast repertoire of piano music. Apart from Alexander Scriabin (1872-1915) in the early 20th century, Prokofiev was one of the composers who continued to engage with this musical form during the mid-20th century. The "Piano Sonata No. 6 in A major, Op. 82," composed between 1939 and 1940, is one of his important works from this period. This sonata is filled with complex emotions related to the war era and exhibits a distinctive musical character. It is regarded as one of the representative works of Prokofiev's compositional style.

This thesis will focus on the "Piano Sonata No. 6 in A major, Op. 82" as the subject of discussion and research, exploring three aspects: "Prokofiev's Life," "The Musical Language of Prokofiev's Piano Sonatas," and "The Analysis and Interpretation of the 'Piano Sonata No. 6 in A major, Op. 82.'" By delving into the theoretical aspects of this work, we can more accurately capture the composer's original intentions. With these theoretical foundations, the author will seek to blend the composer's musical style with their own life experiences and knowledge to interpret a piece of music that retains a sense of self-awareness.
