(Educational Piano Library). Piano Technique Book 2 is the second book in our series of five books focusing on technical skills. Emphasizing the inseperable link between technique and musical expression, Piano Technique Book 2 presents Warm-Ups and Etudes that take the "routine" out of technique! Students are encouraged to build solid technical confidence and skills through short, musical exercises that correlate page by page with Piano Lessons Book 2. Accompaniment audio is accessed online using the unique code inside each 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.
