The Mason Hamlin BB can be difficult, particularly in the alto section over the capo d'astro bar. Don't be shy about really banging them in.

I asked her to let me konw if that ever happens again, but I'm curious as to why the tambre as she called it would go out of tune so quickly if I set the pin which I'm sure I did. The piano is a Mason Hamlin BB. So my question is this and it relates to another piano I'm visiting next week. Can taking a hammer shank and pressing the string around the bridge pin area and also around the hitch pin area help it stay in tune better? The customer I'm visiting next week has a Yamaha GB1 that seems to go out of tune easily after the last technician tuned it. I have not idea who the last person was that tuned it. I believe this is called seating the string, so is pressing it with the hammer shank helpful as I do not have a brass rod now. Or does this simply help with false beats? what about pressing the hitch pin loop? thanks everyone, and thanks for any other help that you've given in the past. I'm not sure if I thanked all of you last time, but in case I didn't I do appreciate your help and ideas. Marshall ps. Today one of the schools I tune for replied to m y reminder for a tuning tellingm e the piano "died." So once I find out what she means, I'll let you guys know. It is a Yamaha Nipponga hmm spell check here nippongacci? Land of the rising sun I think this means I was once told. I'm curious has t how the piano died unless she means an electronic one.
