Marie Stultz has been working with treble-voiced singers for over 30 years. During that time she has developed a philosophy of programming which insures that every song is chosen because it delivers a lesson in a particular one of ten pedagogical areas, according to the needs of the choir. The book explains Ms. Stultz's theories about repertoire selection, and how to use the website. The website, to which you receive a one-year subscription when you buy the book, is an extensive annotated bibliography in the form of an easy-to-use searchable database of repertoire for treble voices. Each annotation gives all the practical information about the song or movement as well as an explanation of how it can be used in rehearsal and performance, along with a list of specific teaching tips. Many of the pieces of music are suitable for the advanced female ensemble in school, church or community settings. Ms. Stultz is constantly adding annotations to the site so you will want to log on often!
