Alfred's Basic Piano Library. Alfred's Basic Prep Course, Lesson Book A is specifically designed for beginners who are five years old and up. Through the use of appealing music and attractive illustrations, it is no wonder that Lesson Book A is the most widely used young beginner's piano book now available. This course takes into consideration the normal attention span, as well as the small-sized hands of the young beginner. Shortly after beginning, the young student will be able to play "Merrily We Roll Along." The complete Prep Course consists of six books (Levels A through F). For a limited time, a CD is included FREE with the purchase of Lesson Book A (while supplies last).
