The soundtrack consisted of compositions from Bernstein's musicals and operettas such as West Side Story, Candide, On the Town, Mass, Chichester Psalms and Symphonies Nos.

Apart from that it also featured works from Gustav Mahler, Ludwig van Beethoven, W. C. Handy, Robert Schumann and William Walton that were used to illustrate key moments in Bernstein's career and marriage.
