Show tunes are songs written for stage musicals and revues, designed to advance plot, reveal character, or provide memorable set‑piece moments. They favor strong, singable melodies, clear structures (often AABA 32‑bar or verse–chorus), witty and narrative lyrics, and orchestrations that support drama and choreography. While rooted in the Great American Songbook, show tunes draw on operetta, vaudeville, ragtime, jazz, and popular songcraft, and they are typically performed by stage voices (from legit to belt) with pit orchestras. Because many became popular standards beyond the theater, show tunes occupy a central place in American popular music and are frequently adapted for cabaret, big band, and vocal jazz.

Musical (musical theatre) is a narrative stage form that integrates songs, spoken dialogue, acting, and dance to tell a story. Its core aim is dramatic storytelling in which music advances plot, deepens character, and shapes emotional arcs, often through recurring motives and reprises. Developed primarily on Broadway (New York) and later the West End (London), the genre blends operetta’s melodic lyricism, vaudeville’s variety entertainment, revue’s song-driven showcase, and Tin Pan Alley’s popular songcraft. Musicals range from intimate chamber pieces to large-scale "megamusicals," and from traditional book musicals to rock, hip‑hop, and concept-driven works. The musical’s songbook has fed the Great American Songbook and popular music at large, while the stage craft has influenced film, television, and concert performance.
