If your choir can sing up and down the scale, they're ready to dive into this series! Each exercise is limited to a brief eight measures, so one or two a day should easily fit into your available time. Each volume contains 30 pages of choral exercises, presented in both open and closed score, progressing sequentially from completely step-wise and diatonic melodies to more difficult intervallic leaps and rhythms in virtually all keys, both major and la-based minor. The Four-Part edition volumes are available in three different versions: SATB, SSAA and TTBB. This series can also be used by solo singers or by choir members on an individual basis and all five volumes are fully compatible with the parallel unison, two- or three- part versions. Fully reproducible, and available as a digital download, this comprehensive series provides an exhaustive library of sight-singing material that is useful year after year.
