Grofé's most memorable arrangement is that of George Gershwin's "Rhapsody in Blue", which established Grofé's reputation among musicians. Grofé took what Gershwin had written for two pianos and orchestrated it for Whiteman's orchestra. He transformed Gershwin's musical canvas with the colors and many of the creative touches for which it is so well known. He went on to create two more arrangements of the piece in later years. Grofé's 1942 orchestration for full orchestra of "Rhapsody in Blue" is the one most frequently heard today. In 1928, Gershwin wrote a letter to ASCAP complaining that Grofé had listed himself as a composer of "Rhapsody in Blue". The dispute was settled, with Grofé receiving a portion of the music royalties for the piece. Despite this misunderstanding, Grofé served as one of the pallbearers at Gershwin's funeral in 1937.
