Hi, I recently had 4 different jobs tuning 6'11" to 7' grands (Steinway, Yamaha and Baldwin). With each of the pianos I had the same problem. I would use short, sharp "jerks" on the tuning hammer to bring a string to pitch. I would feel the pin move (not twist but actually move) but the pitch wouldn't change. Then suddenly on the 5th or 6th stroke the pitch would jump quite a bit above where I wanted it to be. When I tried to lower it to the correct pitch the would stay put and then leap back down below where I wanted it. Eventually I was able to get it to the right spot but it was all very frustrating. Is there a special (or different) hammer technique that one should use with the larger grands or did I just manage to get 4 difficult pianos? Thanks for the help. Sherry
