Lay the foundation for successful part-singing with this unique and valuable resource designed to aid music teachers by providing a step-by-step path for teaching young choirs how to sing harmony, building a bridge that transitions between elementary and high school music reading. Perfect for middle school, this resource can be easily adapted for younger and older singers. Each step in this book offers several songs that will give choirs the practice they need to master each type of harmonization. The enclosed CD-ROM includes mp3 recordings of piano accompaniments and PDFs of the piano/vocal scores for projection or printing. The progressive steps used to teach harmonization involve these familiar song styles: unison, ostinato, echo songs, descants, partner songs, rounds, polyphonic songs and homophonic songs.
