During a time in cinema history when film music was going through a stylistic shift, jazz was commonly used in place of the Romantic orchestrations popular in films of the 30s, 40s and 50s. Director Woody Allen, a well-known jazz enthusiast, uses some of the most prominent jazz musicians and songwriters in his films from 1969 to present day. The 1979 film Manhattan works as an homage not only to the city it’s named after but also to the well-known New York composer, George Gershwin. No less than ten of Gershwin’s most popular jazz pieces are placed throughout Allen’s film and serve to represent sentimentality and a feeling of nostalgia towards Gershwin’s music and Gershwin’s Manhattan.
Manhattan tells the intertangled love story of four people: Isaac (Allen), a 42-year-old divorced father, Tracy (Mariel Hemingway), Isaac’s 17-year-old girlfriend, Yale, (Michael Murphy) Isaac’s married best friend, and Mary (Diane Keaton), Yale’s mistress. All characters share similar issues of insecurity, loneliness, dishonesty, infidelity and self-importance, and all, save for maybe Tracy, are completely unaware of these flaws.
Gershwin’s music is used as an extension of Isaac’s character but represent a rather unrealistic perception of his life, that is Isaac’s perception of his own life. “Sweet and Low Down” is Isaac’s main musical theme while two different versions of “He Loves and She Loves” are used for Tracy and Isaac’s relationship. During the initial, and somewhat awkward, intimate scene between Isaac and Tracy, “Our Love is Here to Stay” is heard as Isaac explains why Tracy can not spend the night. Isaac and Mary’s relationship is represented by more mature and suggestive pieces of music. The early morning walk that ends at the Queensboro Bridge is accompanied by “Someone to Watch Over Me” while a date to the museum includes a rare orchestral version of “Do, Do, Do.” Both pieces imply a desire for real love and romance that neither character is able to successfully attain.
All of Gershwin’s music is used non-diagetically, outside the narrative, while certain pieces of diagetic music are used to show Isaac at his most uncomfortable moments. The New York Philharmonic plays Mozart’s Symphony No. 40 in G Minor during a double date between Isaac and Mary, and Yale and his wife Emily. Mozart’s music goes through a rapid progression of minor key modulations while Isaac fidgets uncomfortably in his seat, perfectly aware of how awkward his situation is.
In the initial dialogue Isaac works on the first line for his current book: “Chapter One: He adored New York City. To him it was a metaphor for the decay of contemporary culture.” In Manhattan, the music serves as a metaphor for everything in Isaac’s life. His insecurities, his love for Tracy, his feelings for Mary, his relationship with Yale, his animosity towards his ex-wife, his love for his son and his nostalgic affection for Manhattan. He dreams of the days of Gershwin, contemplating how simple life must have been when the music was “S’wonderful.”
