Are you sure about this? Can you post a reference? My understanding is that the same sorts of scales (logarithmic, with any frequency f and f*2^n treated as equivalent pitches, usually with five or eight tones per octave, occasionally more) have arisen independently in just about every human culture, usually without a mathematical theory. I could be wrong, though.
