Ruby (Ruby Gentry theme)

The "Ruby Gentry theme," often simply referred to as "Ruby," is a popular instrumental piece composed by Maxwell Steiner. It served as the main theme for the 1952 film noir drama Ruby Gentry, starring Jennifer Jones. The piece is characterized by its haunting, melancholic melody and lush orchestral arrangement, evocative of the film's themes of ambition, social class, and tragedy in the American South. It features prominent use of strings and woodwinds to create a sense of yearning and emotional depth.

While Steiner composed the score for the entire film, "Ruby" became a standalone piece of music, experiencing widespread popularity beyond its cinematic origin. It has been recorded and performed by numerous artists across various genres, including instrumental ensembles, jazz musicians, and vocalists (often with lyrics added later). The piece's enduring appeal stems from its strong melodic hook and its ability to conjure a specific atmosphere of romantic despair and Southern gothic ambiance. The "Ruby Gentry theme" has contributed significantly to the film's legacy and remains a recognizable piece of American film music.
