Beethoven's Piano Concerto No. 5 in E-flat major, Op. 73, known as the "Emperor Concerto," was composed in 1809 and premiered in 1811. This concerto is celebrated for its grandeur and heroic character, featuring bold melodies and innovative orchestration that reflect Beethoven's mature style. Beethoven's Piano Sonata No. 7 in D major, Op. 10 No. 3, composed in 1798, is notable for its four-movement structure, including a deeply expressive slow movement that foreshadows his later, more tragic slow movements.
