Alfred Premier Piano, Theory Book 5
By Dennis Alexander, Gayle Kowalchyk, E. L. Lancaster, Victoria McArthur, and Martha Mier
 
From the publisher (Alfred Music):
The activities in Theory Book 5 continue to develop the theoretical knowledge begun in previous levels of the course. A balanced mix of necessary drill with activities that stimulate creativity, including harmonization and composition, makes theory motivating and fun for students. Written theory is interspersed with activities that foster sight-reading and ear-training skills, while intriguing comments on music history and style reinforce the theoretical principles.
