Edvard Grieg completed his only concerto for piano in 1868 when he was just 25 years old! It was premiered in Copenhagen in 1869.
Grieg’s Piano Concerto is in three movements and is a little less than half an hour long.
Grieg was a huge fan of Robert Schumann, who composed his only piano concerto just ten years earlier. There are similarities between Schumann’s concerto and Grieg’s, including both being in the key of A minor, and general stylistic similarities. For this reason, they are sometimes confused with one another even though Grieg incorporated Norwegian folk elements into his concerto.
Intermezzo and The Seventh Veil, the Broadway musical How to Succeed in Business Without Really Trying, a Jethro Tull tour, and the video game Civilization V. The one that has fortunately/unfortunately stood the test of time for some of us is the early 80s aerobics album Hooked On Classics. Look for it there (around the 3:45 mark), nestled between the "Hallelujah Chorus" and "March of the Toréadors". You’re welcome.
This piece is one of the most popular and consistently performed piano concertos. As such, it has also made its way into numerous popular culture references including the films
Grieg’s score calls for solo piano, 2 flutes, 2 oboes, 2 clarinets, 2 bassoons, 2 horns, 2 trumpets, 2 trombones, tuba, timpani, and the usual string section of violins, violas, cellos and basses. It pretty much looked like a musical Noah’s Ark until he later changed it to add 2 more horns and converted the tuba to a third trombone. Maybe that’s also what happened to the unicorns...
