The Piano Concerto in A minor, Op. 16, composed by Edvard Grieg in 1868, was the only concerto Grieg completed. It is one of his most popular works and among the most popular of all piano concerti.
The concerto is in three movements:
Performance time of the whole concerto is usually just under 30 minutes.
The concerto was originally scored for 2 flutes, 2 oboes, 2 clarinets in A and B flat, 2 bassoons, 2 horns in E and E flat, 2 trumpets in C and B flat, 2 trombones, tuba, timpani and strings (violins, violas, cellos and double basses). He later added 2 horns and changed the tuba to a third trombone.
The work is among Grieg's earliest important works, written by the 24-year-old composer in 1868 in Søllerød, Denmark, during one of his visits there to benefit from the climate.
Grieg's concerto is often compared to the Piano Concerto of Robert Schumann — it is in the same key, the opening descending flourish on the piano is similar, and the overall style is considered to be closer to Schumann than any other single composer. Incidentally, both wrote only one concerto for piano. Grieg had heard Schumann's concerto played by Clara Schumann in Leipzig in 1858 (1859 is given by alternative sources), and was greatly influenced by Schumann's style generally, having been taught the piano by Schumann's friend, Ernst Ferdinand Wenzel.
