Nominally it would be about 16Hz. Take C5, which is about 513 if memory serves, and divide by 2 5 times in succession. A0 is nominally 27.5 Hz (440 divided by 2 4 times). Once you get down that low, it is more of a "beat" than a pitch. And not much fundamental is produced. It's the partials you actually hear. Regards, Fred Sturm It's interesting that you mention the fundamental not being "heard". A man in the chorus in which I sing told me that humans cannot hear a pitch that low, but that we only hear the partials. When I tuned one once, I remember hearing the actual vibrations of the strings, which to me sounds like a B19 Bomber, but I can't remember if I was actually hearing the fundamental, or just the overtones.
