In some ways, the successor of vaudeville and an extension of the opera and operetta, the stage musical has evolved into a worldwide juggernaut. Musicals are staged not only across the globe but are offered in a variety of settings, from the high school stage and major theater to the big screen. The stage musical has become a staple for the professional singer and the object of close study by students of singing. In So You Want to Sing Music Theater: A Guide for Professionals, singer and scholar Karen S. Hall fills an important gap in the instructional literature for those who sing or teach singing to those seeking their fortunes in music theatrical productions. Developed in coordination with the National Association for Teachers of Singing, this work draws on current research from the world of voice scholarship to advance the careers of singers seeking to make a foray into or already deeply embedded in the world of music theater.
