Already Seebeck was wrongly blamed wrong for the sake of an immature theory. (Recall: Ohm dismissed Seebeck's discovery of an audible missing fundamental, and Seebeck 1844 replied that the word illusion was inappropriate since only the ear could decide how tones should be heared.) Having suggested a joint autocorrelation mechanism including a real-valued first cochlear analysis as well as a subsequent also real-valued analysis within brain, I would appreciate any study or comment on the possibility that the predominant physical correlate to pitch is not really frequency but something like autocorrelation lag. I just amended http://iesk.et.uni-magdeburg.de/~blumsche/M277.html Be not mislead by further imperfections. My basic ideas might nonetheless be correct. Eckard Blumschein
