The Art and Practice of Musical Theatre Choreography by
What does a musical theatre choreographer actually do? They just 'make up the steps', right? This book firstly debunks the misunderstandings around what musical theatre choreographers actually do, demonstrating their need to have an in-depth understanding of storytelling, music theory, performance practices and plot structure in order to create movement that enhances and enlivens the musical. Secondly, it equips the musical theatre choreographer with all the tools needed to create nuanced, informed and inspired movement for productions, through structured activities that build specific skills (such as 'notating the script' and 'scoring the score'). Traditionally, this training has been something of a series of secrets, passed from mentor to apprentice. The author demystifies the process to make the previously undisclosed "tricks of the trade" accessible to all choreographers, everywhere. Covering the entire process of choreographing a musical from the first script reading to the final curtain call, this book makes case for the absolute integrity of the choreographer to any musical theatre production and sets out the theoretical principles of choreography alongside the practical application during every step of the production process.
