... Yes. However what you can do is to filter out the all but the strongest harmonic, and count which harmonic number it is.
how do you know what the harmonic number is? how would that information be determined in the general case.
Then you know how many zero crossings it has in an period of the fundamental and can count them. Of course with the piano, since they are not harmonically related this will give a small error. However the lowest ones are not too far out, (and besides the ear the actually uses all of the harmonics to decide on the pitch it will present to you).
well, the frequencies of the higher harmonics are a little sharp. i think that affects the perceived timbre of the sound but not so much the pitch.
