This album brings together piano sonatas by Mendelssohn, Beethoven, and Schumann that reflect a specifically German approach to the form, distinct from the Viennese Classical tradition. Pianist Tianxu An explores works composed within a 26-year span, a period in which composers redefined the sonata through structural experimentation and greater performative expression. Central to the recording is a focus on the composers' detailed markings, including dynamics, pedalling, and phrasing, and how these shape interpretation in performance. Recorded in 2024, the release presents An's considered engagement with this repertoire and his interest in it's intellectual rigour and expressive breadth.
