Reinhardt: Have had similar problems with three other grand pianos during the last 6 months. The "fix" was identical for all three pianos.....glue touching the nose bolt...causes strange things to pianos.....one technician drove a "stob" between the bracing and soundboard to attempt to stop the buzzing. Of course there are many problem areas...Some technicians suggest a stethascope (spelling???)....auto mechanics use them...I have never used one BUT they say one can locate the problem with this device....Good luck....
