I had a similar experience a few years ago, but with a dog. As I was tuning, the owner's black lab would begin to howl, then slide up or down to the correct pitch and stay there! The process would be repeated with the next note. We put her outside and she would do the same thing from outside the front door. Another time I encountered a schnauzer that would take up residence under the grand I was tuning and howl loudly the whole time. Not on pitch though. He was taken outside the room and stopped making noise. His owner said it would do the same thing whenever anyone played the piano. Mike Kurta, RPT Chicago chapter
