Jerry Livingston composed "Under a Blanket of Blue" in 1933, with lyrics by Marty Symes and Al J. Neiburg. The song emerged during the early 1930s Tin Pan Alley era and became a popular standard of the period. Its melody is warm and gently swinging, with a romantic sentiment that evokes a starlit evening, as the lyric paints an image of lovers together under the night sky. The harmonic language is characteristic of the era's popular songwriting, with smooth voice leading and accessible chord progressions that invite both vocal interpretation and instrumental improvisation. Glen Gray and the Casa Loma Orchestra had an early hit with the tune, helping establish it in the popular repertoire. The song attracted attention from jazz musicians as well, with artists finding its changes well-suited to improvisation. Though not as widely performed today as some of its contemporaries from the 1930s, it has maintained a presence in the jazz vocal repertoire. The 1956 recording by Ella Fitzgerald and Louis Armstrong for their landmark Verve album paired two of the most celebrated artists in jazz history, with Armstrong contributing a characteristically expressive trumpet solo that highlights the tune's melodic charm. Livingston went on to a prolific career in film and television music, but this early song remains among his most enduring contributions to the American popular songbook.
