Rogerio, Don't believe everything you read. 4 cents is approximately 1cps only in the range close to A440. There are 1200 cents in an octave. The octave from A220 to A440 spans 220 cps, the octave from A440 to A880 spans 440 cps. Thus, with a little bit of analysis, we must conclude that the ratio of cents to cycle is higher below A440 than above. I will contact the Shiller Institute forthwith. Your previous post was thought provoking to say the least. Please don't let a little friendly disagreement discourage you.
