Part Exercises. This supplemental volume of part exercises follows the sequence of The Jenson Sight Singing Course, but can be used in conjunction with any sight singing method. It has been compiled to provide choral directors with graded material in parts for use with choral ensembles, and consists of predominantly 4-part exercises, along with rounds, 2-part and 3-part exercises. Ranges allow for flexibility in voicing for various groups. Available in the Jenson Sight Singing Course: Teacher's Edition Vol.I & II, Student Edition Vol. I & II, and Sightsinging Part Exercises. For Grades 6-12.
