"My Foolish Heart" is a ballad composed by Victor Young with lyrics by Ned Washington for the 1949 film of the same name. Young, one of Hollywood's most celebrated melody writers, also scored the full film. The song was introduced by Martha Mears, who dubbed the singing voice for actress Susan Hayward, and it earned an Academy Award nomination for Best Original Song in 1950, losing to "Baby, It's Cold Outside." The composition follows an ABAC form across 32 bars and is built on "ice cream changes," the familiar I-vi chord progression shared by tunes like "Blue Moon" and "Heart and Soul," though secondary dominants and a distinctive flat-VI chord via modal interchange give the harmony its own character. Gordon Jenkins and His Orchestra recorded the original version in 1949, and the tune initially circulated more as a vocal piece before gaining traction with jazz instrumentalists. Gene Ammons recorded an early tenor saxophone reading in 1950, followed by important versions from Carmen McRae, Andre Previn, and Ray Brown in 1956. Bill Evans's piano trio performance at the Village Vanguard, captured on the 1961 album Waltz for Debby, became the definitive jazz interpretation, notable for its sophisticated reharmonizations including II-V substitutions and backdoor cadences. Evans returned to the tune in a 1975 duet recording with Tony Bennett. The song remains one of the most frequently performed ballads in the jazz repertoire.
