This is a slightly tongue-in-cheek post, reminiscent of the G-sharp
versus A-flat debate!
I hope my RW article shows that the link between nominal frequency
and bell pitch is not as certain as we all believed. The biggest
discrepancy I have seen so far in a 'normal' sized bell is Southwold
treble, where the difference is about 1/3 of a semitone.
However, we all know that in big bells the 'secondary strike' gives a
much larger divergence. On what basis do we describe a bell such as
Big Ben as E + 27 (i.e. 335.1 Hz) when the note we hear is clearly
the A above this? :-)
