Sing to Me in F Sharp...

 My love for gadgets came from my Grandfather. We both used to get a little too excited over cameras and wristwatches. So when my parents gave me an Accutron as a High School graduation present (and after I had pestered them endlessly about it), Grandpa was green with envy. it kept time with a tuning fork that used a "360 herta tuning fork instead of a balance wheel as the timekeeping element. That was both innovative and groundbreaking at the time. (Yes, I just said that.) Grandpa started salivating and ran right out to buy one for himself. With that tuning fork, if you pressed it to your ear, you could hear it humming an F sharp. In the summer of 1966, I toured England with the church choir that I had sung in since I was 7 years old. When we hit Westminster Abbey to sing a capella for the Queen, our choir master realized that he had lost his pitch pipe. He had me listen to my watch and hum an F sharp. Scaling it up or down from there he hummed the proper note for us to start on. I told my Grandfather about the F sharp, but at his age he had lost all hearing in the upper ranges and just had to take my word for it. He still loved his Accutron though and enjoyed telling people that his wristwatch was always singing... in F sharp...
