List: Today I tuned a Tadashi grand, probably less than 10 years old, with no visible faults. During the tuning, I noticed something I haven't experience before, and I hope maybe someone out there can help me with it. This piano makes a sound like a drum when the keys are played. It's not a dull thump or a crack like might come from a warped keyframe knocking on the bed. This is more of a "poom" sound, with a definite pitch (about that of a tom-tom in a trap set), and about a half-second sustain. No hint of a rattle, just a poom. I investigated further. I thumped the bottom of the keybed with a closed fist. Poom. I went around the rim, pounding with closed fist. Poom. Poom. Things seemed to quiet down as I moved toward the back of the rim, near the bass bridge, then liven up again as I continued around the rim... This was my first time on the piano, and the customer wasn't home. But this intriges me, because in 15 years of tuning I've never heard anything like it. And in case I get asked to track it down, I need some ideas about where to start looking. Any suggestions? John Granholm Granholm Bros Piano Rejuvenations Roseburg, OR gbros@term.wanwb.net
