In 1811, Beethoven composed the Piano Trio “Archduke” in B Flat Major, Opus 97. This piece is one of Beethoven’s supreme achievements in music and a landmark work for piano, violin, and cello. In order to provide a comprehensive study of the “Archduke” Trio, this paper will examine its compositional background and analyze the work’s form, thematic unity, rhythmic figures, and harmonic structure. As a whole, the trio lacks traditional sonata arrangements, though its unified by tightly interrelated thematic motives and underscored by polyphonic textures, different rhythmic patterns, and dramatic alternation of harmony. Performers who play this piece should be able to maintain steady rhythms and be keenly aware of changing tempos, alongside the ability to engage with the mood and emotion presented by the ensemble. Only then will the performer be able to fully express the emotional depth and spectrum of this work.
