(Educational Piano). Physical training and discipline are needed for both athletics and keyboard playing. Keyboard muscle conditioning is called technic. Technic exercises are as important to the keyboard player as workouts and calisthenics are to the athlete. Schaum's Fingerpower books are dedicated to development of individual finger strength and dexterity in both hands. This edition includes access to online recordings of each exercise. Audio is accessed online using the unique code inside the book and can be streamed or downloaded. The audio files include PLAYBACK , a multi-functional audio player that allows you to slow down audio without changing pitch, set loop points, change keys, and pan left or right.
