Book excerpt: Milestones in Musical Theatre tracks ten of the most significant moments in musical theatre history, from some of its earliest incarnations, especially those crafted by Black creators, to its rise as a global phenomenon. Designed for weekly use in musical theatre courses, these ten chosen snapshots chart the development of this unique art form and move through its history chronologically, tracking the earliest operettas through the mid-century Golden Age classics, as well as the creative explosion in directing talent, which reshaped the form and the movement toward inclusivity that has recast its creators. Each chapter explores how the musical and its history have been deeply influenced by a variety of factors, including race, gender, and nationality, and examines how each milestone represents a significant turning point for this beloved art form. Milestones are a range of accessible textbooks, breaking down the need-to-know moments in the social, cultural, political, and artistic development of foundational subject areas. This book is ideal for diverse and inclusive undergraduate musical theatre history courses.
