Piano Concerto No. 3 (Hummel)
Unlike his earlier piano concerti, which closely followed the model of Mozart's, the B minor concerto along with the slightly earlier Concerto No. 2 is written in a proto-Romantic style that anticipates the later stylistic developments of composers such as Frédéric Chopin and Felix Mendelssohn. 
Date of composition and scoring
The piano concerto was written by Hummel as a showcase for his virtuosity at the instrument. It was written while the composer was in Vienna in 1819 and is scored for piano, flute, two oboes, 2 clarinets in A, 2 bassoons, 4 horns in D, G, and B, 2 trumpets in B, timpani, and strings. Notable is the sparsely scored second movement nocturne, accompanied by only the horns, cellos, and basses.
The work is composed in traditional three movement form.
