Ferdinand Rudolph von Grofé, known as Ferde Grofé was an American composer, arranger, pianist, and instrumentalist. He is best known for his 1931 five-movement symphonic poem, Grand Canyon Suite, and for orchestrating George Gershwin's Rhapsody in Blue for its 1924 premiere.

In music, an arrangement is a musical adaptation of an existing composition. Differences from the original composition may include reharmonization, melodic paraphrasing, orchestration, or formal development. Arranging differs from orchestration in that the latter process is limited to the assignment of notes to instruments for performance by an orchestra, concert band, or other musical ensemble. Arranging "involves adding compositional techniques, such as new thematic material for introductions, transitions, or modulations, and endings. Arranging is the art of giving an existing melody musical variety". In jazz, a memorized (unwritten) arrangement of a new or pre-existing composition is known as a head arrangement.
