The Piano Concerto in A minor, Op. 54, is a Romantic concerto by Robert Schumann, completed in 1845. The work premiered in Leipzig on 1 January 1846 with Clara Schumann playing the solo part. Ferdinand Hiller, the work's dedicatee, conducted.
Schumann had earlier worked on several piano concerti: he began one in E-flat major in 1828, from 1829–31 he worked on one in F major, and in 1839, he wrote one movement of a concerto in D minor. None of these works were completed.
In 1841, Schumann wrote a fantasy for piano and orchestra, his Phantasie. His pianist wife Clara urged him to expand this piece into a full piano concerto. In 1845 he added the intermezzo and finale to complete the work. It was the only piano concerto that Schumann completed.
The work may have been used as a model by Edvard Grieg in composing his own Piano Concerto, also in A minor. Grieg's concerto, like Schumann's, employs a single powerful orchestral chord at its introduction before the piano's entrance with a similar descending flourish. Rachmaninov also used the work as a model for his first Piano Concerto.
After this concerto, Schumann wrote two other pieces for piano and orchestra: the Introduction and Allegro Appassionato in G major (Op. 92), and the Introduction and Allegro Concertante in D minor (Op. 134).
The concerto is scored for 2 flutes, 2 oboes, 2 clarinets, 2 bassoons, 2 horns, 2 trumpets, timpani, strings, and solo piano.
