Morning Mood was written by Norwegian composer Edvard Grieg as part of his 1875 incidental music for Henrik Ibsen's play Peer Gynt. It later opened Peer Gynt Suite No. 1, Op. 46, and became one of Grieg's most familiar works. The piece was meant to depict a sunrise over the desert as Peer wakes alone. Through cartoons, films, adverts and classroom listening, its opening bars became a universal shorthand for morning itself, which is why students and editors still search for it for projects.
