I have a spreadsheet which shows the distance between each note in hertz (cps) and how many cps/cent and cents/cps. Around A4 there are approximately 4 cents/cps. The distance between A0 and A#0 is ~1.6 hertz; 1.6/100 = 62.5 The distance between A7 and A#7 is ~209 hertz; 209/100 = .48 It is around the middle of the 6th octave where 1 cent = 1 hertz The note frequencies were supplied by Stephen Birkett, hence the historical notation. If you would like a copy of the Excel spreadsheet please e-mail privately by clicking on the link in my signature.
