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. The price of this book includes a unique code that provides access to audio tracks online, for download or streaming. The tracks 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 - available exclusively from Hal Leonard.
