Book with Audio Files & Flash Cards . This is a one year piano/keyboard course that is comprehensive and lots of fun. It incorporates a broad range of styles such as rock jazz and classical. The learning sequence is the same as for the Junior series but with alternative repertoire. Each book comes packaged with audio files featuring "play-along" arrangements of all the pieces. Also included are Rhythym Taps to assist in the development of 2-handed rhythym reading and playing plus Finger Taps to establish finger numbers and patterning. Students who successfully complete the Encore on Keys Primary Series advance to the Achiever Series.
