Drawing on the original G. Schirmer edition, this new G. Schirmer edition in the Hal Leonard Student Piano Library was created with today's developing pianist in mind. This fresh look at Hanon's popular studies includes innovative student worksheets; virtuoso variation suggestions; informative historical and biographical facts; chromatic-scale exercises, and fully orchestrated accompaniments for each exercise in a variety of styles. The 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.
