In SoYou Want to Sing Barbershop, veteran barbershoppers Billy J. Biffle of the Barbershop Harmony Society and Diane M. Clark of Sweet Adelines International provide a practical handbook for singers at all levels who want to learn about the American art form known as barbershop singing. Clark and Biffle explore the history of the style, survey the international organizational structure of the twenty-first century barbershop world, and outline techniques to develop the necessary vocal skills for the style. Guest authors Scott McCoy and Wendy LeBorgne provide valuable information on vocal anatomy and vocal health. The So You Want to Sing series is produced in partnership with the National Association of Teachers of Singing. Like all books in the series, So You Want to Sing Barbershop features online supplemental material on the NATS website.
