How many piano strings are hit to play middle c?
The above is, of course, correct for all practical purposes. If you want to get technical (to the point of being downright obnoxious) the is “two” for middle C. In this part of the piano register, no strings (wires) are cut and attached to the far end (the end of the wire opposite the tuning pins). Wires are looped around a hook and come back up to be connected to the next tuning pin. So for a three string note, two of the strings are in fact different ends of the same length of string. And yes, this means that one length of string will serve two different notes!
