This landmark book by one of Germany’s leading authorities on the subject explores the development of hammers and piano actions from earliest times until the present day.  Part one of the book explores different hammer actuation designs, including bumping, pushing, pulling and linked actions.  The second part of the book explains the hammer in its relationship to the jack, the wippen and the key, exploring let-off resistance, hammer weight and kinetic energy, and action transmission ratios.  A must-have reference guide for technicians working to optimize piano touch and inertia.  A reference for anyone interested in historical and rare piano actions, and the evolution of piano actions in general.
