The 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 composers wrote only one concerto for piano. Grieg had heard Schumann's concerto played by Clara Schumann in Leipzig in 1858, and was greatly influenced by Schumann's style generally, having been taught the piano by Schumann's friend Ernst Ferdinand Wenzel.
