---------------------- multipart/alternative attachment Thought for the day: Have you ever put exactly ten pairs of socks into a clothes drier but pulled out only 19 when they were dry? One of those unexplained mysteries in life that has no answer. I was talking with a client who was wondering why grand pianos sometimes develop wear marks on the fall board above the keys. Admittedly I had no definitive answer. I'm sure you have all notice this, particularly above the sharps. Sometimes the wear can be so bad that it can extends well into the wood. But then you have to stop and wonder how they got there. For technical reasons you do not play the piano that close to the fall board. In observing a pianist playing I have never seen any kind of technique that would suggest a reason- even in aggressive playing. Certainly there are other case parts on a piano that receive rougher treatment. Nevertheless somehow these wear marks appear very defined and consistent. So here then is the riddle: How do these marks get there? Is there a particular type of maneuver required by the pianist? Is it avoidable? Can you find the missing sock?
