|Dear Dick, Martin, and others,|
I agree strongly that octave equivalence and the circular dimension needs to be taken into account in any definition of pitch, and that Stevens' 'halving' procedure never made sense. The definition of pitch by the American National Standards Institute as "that attribute of auditory sensation in terms of which sounds may be ordered on a scale extending from high to low" - which implicitly denies the circular component - is simply mistaken, and should be amended.
For a study demonstrating pitch circularity in tones that constitute a full harmonic series, please see:
