Interesting that you should bring this up as I have a customer recently who claims that his 9' piano has too much inclination and wants it altered. It has made me begin to think about what the optimum inclination might be. It will vary from piano to piano and with key length, of course. The piano itself will limit the kinds of changes one can make. For example, by the height of the fall board when in the up position, the thickness of the keyframe at both the back and the front, convergence limits, height of the wippen cushion over the key/capstan position, damper timing consideration, etc.. It seems like the key certainly has to start with an upward inclination. Whether it travels through level and finishes with a downward inclination or finishes at level and then to what degree seems to be the question. Wish I had an answer as I will be having to try and figure out just what the best solution is for this person fairly soon.

I'll bring the topic up again soon. Am I the only one to notice advantages to key inclinations?? -- Regards, Jon Page
