The American musical theater is internationally known due to its entertaining power and its huge popularity. It is a hybrid genre, with European roots, whose organizational methods consolidated into the Broadway-style model for export during the 20th century. The Brazilian musical theater followed a more unsteady path, alternating moments of prestige during the era of the revue, moments of populist or didactic appeal, which is the case of the politically engaged musical, and long off season periods. Since the 1990s, the Broadway model of musical has taken the Brazilian stages by storm, and through showing the classic American musicals, audiences are being educated and familiarized with the conventions of the genre, such as the non-stop transitions between dialog and song and vice-versa. The aim of this research is to highlight the structure of the model that has proven longstanding by the elements that it s made of – book, score – and its variety in form – integrated, conceptual, jukebox – and in this way contribute to minimize the unbalance in quality between the musicals produced by national authors and the Broadway model and to motivate the creation of librettos that will help the Brazilian musical continue on its journey.
