Bill; I think I understand. i.e.-we can hear what is not really there but cannot hear what is really there? :-) Seriously I believe that it is these 'intangible' harmonics (I call them) that makes a "pure" note/tone on a stringed instrument,piano or otherwise, pleasing and the lack of them in the same note on an electronically generated instrument sound flat/lifless. Just an opinion and not based on scientific study. Jim Bryant (FL)
