Here's my story: I was diagnosing a string buzz/ring a few weeks ago. I carefully took note of what had changed since before I heard the ringing: I had tuned the piano, and the temperature had gone up. To make a very long story short, I ended up systematically eliminating causes. I looked for sympathetic vibrations in the room and ended up moving the computer, the lamps, the picture frames, the smoke detector, etc. Nothing. I pulled the action and plucked the strings with a guitar pick. The ring was still there. Then I notice a similar high-pitched ring in the SAME NOTE on two other pianos. Strange, eh? So I searched for "high pitch ring", or something like that, in the archives, and came up with lots of info on tinnitus. Hmmm, _I_ have constant ringing in my ears, I all of the sudden noticed. And I seem to be very sensitive to high-pitched noises all of the sudden. Maybe that has something to do with it... I was relieved to discover at www.ata.org that alergies and sinus problems can be causes of tinnitus. I had forgotten to note my sinuses' acting up when I tried to diagnose my string problem, but I had no idea that might be a factor. I got some ear plugs, the kind that attempt to filter all frequencies evenly, and I was playing the piano with ear plugs for a while because it was hurting my ears to play the piano. Fortunately, the problem seems to be getting better as the alergies are clearing up, but I'll still check with a doctor. I will now always use ear plugs when tuning. I can hear the beats fine with them, and now I can pound the notes harder. My unisons are holding better! So, I got a wake up call to protect my ears. And I also learned that things aren't always as you hear them! Charles Neuman P.S. As it tunred out, there WAS some stuff going on the with the strings as well. Now that I'm not as sensitive to high pitches I can play around with it. I'll ask about it in a separate email.
