Norwegian composer Edvard Grieg is perhaps best-known today for his ten sets of Lyric Pieces for piano. The first of these were begun in 1864 and the last completed in 1901, making them representative of the composer's entire career. Furthermore, these pieces have served as instructional pieces for generations of piano students. These pieces create a variety of moods. Despite Grieg's reputation as a "nationalist" composer, his influence was widespread. Composer Frederick Delius, an admirer of Grieg, once said to Ravel, "Modern French music is simply Grieg plus the prelude to the third act of Tristan." Ravel agreed, admitting that Grieg often did not receive the credit he deserved. Grieg's string quartet is widely seen as a predecessor to Debussy. Composers Percy Grainger and Edward MacDowell also specifically acknowledged Grieg's influence.
