Fresh from his success in Vienna with the Rondo à la Krakowiak, Chopin decided to explore the piano concerto genre where he would compete with a triumvirate of composers then enjoying huge success in the city: Moscheles, Hummel and Kalkbrenner. Dedicated to Kalkbrenner, though inheriting influence from Hummel, the Piano Concerto No. 1 in E minor, Op. 11 is discreetly orchestrated and marries brilliant virtuosity with expressive melancholy. Structurally similar is the Piano Concerto No. 2 in F minor, Op. 21, though here heroism is tempered by a more reflective intimacy that reaches its apotheosis in the beautiful slow movement.
