"It Might as Well Be Spring" is a popular song with music by Richard Rodgers and lyrics by Oscar Hammerstein II, composed in 1945 for the film State Fair. It won the Academy Award for Best Original Song that year and has since become a widely performed standard in both popular music and jazz. The song arose when Hammerstein, writing for a character experiencing restless longing at an autumn fair, remarked to Rodgers that the feeling was like spring fever even though the season was wrong, instantly inspiring the title. The melody is notable for its syncopated, jumpy quality, featuring unexpected chromatic notes and interval leaps that evoke the unsettled energy described in the lyrics. Rodgers originally composed a more legato version but revised it to a punchier, more rhythmically active line to better match Hammerstein's playful imagery of a willow in a windstorm and a puppet on a string. The structure follows a 40-bar AABAC form, expanding on the typical 32-bar standard format with additional sections that give the melody room to develop its restless character. Harmonically, the tune moves through subtle chromatic shifts that complement the melody's nervous energy without becoming overly complex. It was introduced on screen by Jeanne Crain in the 1945 film and has been recorded extensively by jazz and vocal artists, establishing it as a durable piece of the American songbook.
