Franz Joseph Haydn ： Sonata No.9 in D-Dur Hob.XVI:4

This sonata combines a concise, clear style with approachable melodies and finely shaped musical dialogue. Its several movements each have a distinct character, and the contrast between lively motion and more gently singing passages shapes the overall flow. Highlights include the balance between bringing out the main melody and keeping the accompaniment light, the natural breathing created by phrase divisions, and the subtle changes of expression within repeated passages. In performance, avoiding a heavy touch while maintaining clear articulation and a poised rhythm allows the music’s wit and elegant lightness to emerge. Decorative notes should also be handled carefully, following the direction of the melody without disturbing its flow.
