Choral rounds have been used for recreational singing for hundreds of years and are effective tools for your students to understand harmony, expand their vocal ranges, and experience a choral sound that is easily accessible to them. By using rounds as warm-ups, you can teach vocal technique and music theory, application, appreciation, and history while increasing your singers' understanding of scales, intervals, modes, dynamics, and terminology. Each round in this collection has instructions on the musical focus and implementation of each song, and several were intentionally included for adolescent boys with a limited range. Includes both familiar and rare, easy and challenging, and serious and fun rounds that teachers and students alike will enjoy using to create beautiful and harmonious music together!
