Something interesting happened to me during a tuning last week. It was the first tuning of the day, and my second brain cell hadn't kicked in yet, so I was even less alert than usual. After the opening banter with the owner, I had strip muted the piano, struck my fork, and had it to my ear when she walked past just behind me. Waw-aow-weow-wuh-wa-wa! Wow, now that was interesting. Doppler shifted echoes from my fork bouncing off a moving person. I had never had that happen before with a tuning fork. I've played around with an Accu Fork like this, and noticed it in churches with the organ, but folks usually stand around very still, have hidden in a remote part of the house, or are off to find the vacuum cleaner as I start tuning, so I hadn't noticed it with the fork before. I know, I'm easily entertained. Ron N
