Hi, A few days ago a buzz developed on my piano when playing a couple of notes (E5 and F5). While trying to figure out what was causing it I noticed that if I applied a little pressure to the soundboard from underneath the buzz would go away. Though for the next 2 days the sound was gone, so I just figured it was one of those strange sounds that pops up for no discernible reason. Then today, it is back, but worse. More notes and louder. I isolated the sound to the left side of the soundboard (while facing the keys), maybe about midway back, right about where there is a hairline crack that doesn't go entirely through the board. Again, pressing on the soundboard would help. I looked on top and underneath to see if I could spot loose ribs, glue, etc., but nothing. Any ideas, fixes? Thanks. - John
