This text investigates the physiological and psychological barriers to fluid piano performance and proposes methods for achieving technical ease. Joan Last, an experienced piano pedagogue, draws upon decades of teaching experience to construct a framework for movement that prioritizes relaxation and the elimination of unnecessary tension. The book argues that technical proficiency is not merely a product of repetitive drill, but of understanding the natural mechanics of the hand and arm in relation to the keyboard.

Pedagogues frequently cite this work as a foundational resource for understanding the physical mechanics of piano playing. Experts highlight the clarity of the author's instructions, noting that the text remains highly relevant for both teachers and students seeking to prevent strain.
