Hello Alan Forsyth Your table and jpegs are of great interest. At risk as I may be for asking... How did you derive the figures in TABLE 1 ? Application of that "small formula" to H#1 for the +1 semitone does not give 466 derived from 441, but 467.225... Yet application of (f) on 440 gives 466.163...(etc) which is closer to your figure. Going in a downward direction (pitch-wise) the figures you give in the table are even wilder, aren't they! Did you have a frequency meter and read these partials direct? surely so - they couldn't have been computed... could they ?? :-) Regards Michael G (UK)
