Duke Ellington composed "Solitude" in 1934, reportedly writing the piece in roughly twenty minutes while standing in a Victor Records studio in Chicago. His orchestra had arrived with only three tunes prepared for the session, and while waiting for the previous band to finish, Ellington leaned against the studio's glass enclosure and rapidly sketched out the score. Trumpeter Arthur Whetsel, who played lead on the first recording, suggested the title. Eddie DeLange wrote the lyrics, with Irving Mills also receiving a lyricist credit, a common arrangement given Mills's role as Ellington's manager and publisher. The song's original Victor recording was made on January 10, 1934, though it was not issued until later that year. A second version recorded for Brunswick in September 1934 became the one that charted. Despite being labeled a foxtrot upon release, the composition is unmistakably a contemplative ballad, its melody conveying quiet resignation and loneliness rather than the brightness typical of dance music. The harmonic language is sophisticated, with unexpected turns that deepen the emotional weight of the piece. "Solitude" became a durable jazz standard, recorded by artists including Billie Holiday, who made it one of her signature songs, and Louis Armstrong. It stands alongside "Mood Indigo" and "Sophisticated Lady" as one of Ellington's defining ballad compositions, valued by instrumentalists and vocalists alike for its introspective character and harmonic depth.
