Dear Friends, I will be teaching a course on the evolution and technical aspects of the piano in an adult continuing education program this fall. I would like to be able to show diagrams or pictures of the different piano actions over the centuries but I have not found an easy source of these except in books I am reluctant to scan. If anyone knows where I can get such drawings for down load I would greatly appreciate it. clavichord harpsichord Christifori etc. Newton
