"In a Mellow Tone", also known as "In a Mellotone", is a 1939 jazz standard composed by Duke Ellington, with lyrics written by Milt Gabler. The song was based on the 1917 standard "Rose Room" by Art Hickman and Harry Williams. Howard Stern formerly used a Count Basie version of this song as the opening theme to his syndicated WXRK-FM radio show in the early 1990s.
