When rock music began to appear on Broadway in the 1960s with Bye Bye Birdie and Hair, it opened up the door for new styles to be notated into musical theater scores. Since then, a wide variety of rock and pop genres have been incorporated into Broadway shows. Musical theater scores are representations of the show structure, and how rhythm and syncopation are notated in musical theater score affects how they are interpreted and performed.The past twenty years have seen a growth in popularity of both revivals and jukebox musicals. A revival is a show that appears on Broadway again after the original production; jukebox musicals take an already produced pop rock album or artist and create a loosely structured narrative around it. By analyzing rhythmic notation and syncopations in revivals and jukebox musicals, this paper demonstrates how popular culture and rhythmic notation interact with each other to create complexity in musical scores and performances. Centering around the musical Godspell as a core example, this paper examines rhythmic notation in pop rock musical theater, investigating how revivals and jukebox musicals can contribute to increased rhythmic complexity in scores. This paper articulates the possibilities of a rhythmic notation system that would simplify the complex and frequent syncopations in pop rock musical scores. Eastman professor David Temperley’s work in rock syncopation and deep structure representation is discussed as it relates to musical theater scores. Expanding on Temperley’s theoretical foundation, the appendices demonstrate a proposed original arrow notation with an original song composed for these research purposes.
