Accelerando Book 1, which includes 72 studies for beginning piano students of any age, may be incorporated from the first piano lesson. To ensure the even development of all fingers, the majority of the studies in Book 1 are written for one hand at a time. The deliberate placement of left-hand-alone studies on left pages, and right-hand-alone studies on right pages, unifies and reinforces the concepts of left-right, bass-treble, and low-high keyboard registers.
