<P> The relatively new Taylor tenor at Ludlow also sounds sharp when rung with the others.

On analysing these peals I have <BR>generally found that the nominals were spot on. Now, bellfounders <BR>will assume that the pitch of each bell (the note you hear when it <BR>rings) is half the nominal frequency, and that if the nominals are <BR>spot on the bells will sound 'in tune'. However, academic research on <BR>non-bell sounds suggests that if partial frequencies are not exact <BR>harmonics - such as is the case in old-style bells - the pitch is <BR>related in a complicated way to all the partial frequencies, not just <BR>to one of them.

Therefore, we actually assign a slightly different <BR>note to the same bell.
