A) = 27.5 cps C8 = 4186 cps No one has mentioned that these frequencies are just the fundamental frequencies of the low and high keys on a piano. While the piano does not make lower tones than this that we would need to hear, it does make higher ones. The harmonics, or rather partials, of notes in the melody range up to the top certainly go higher. If you look at it this way, or listen to it as a healthy musician's ear would, much higher. A healthy ear will hear musical sound from a piano at least up to 20,000 cps. Music recordings normally go at least that high. This of course does not mean that a tuner with hearing loss cannot do his job; he/she can learn to compensate. I think this is a more accurate answer to the original question; 16,000 cps may be as high as some of can hear, but the piano can produce higher frequencies than that.
