Let us turn now to symmetrical Western bells. The spectrum of a bell is inharmonic. The following table, adapted from Bill Hibbert's [https://www.hibberts.co.uk/building-a-bell-sound/ ''Building a bell sound''] talk, gives the names for each partial along with their frequencies measured for a particular bell: <ref name="hibbert2021building"/> | Let us turn now to symmetrical Western bells.

The strike pitch is the perceived fundamental pitch of the bell sound; it does not necessarily coincide with one of the partials, and varies from person to person, but is typically around an octave below the partial called the nominal. <ref name="hibbert2008quantification"/> | The strike pitch is the perceived fundamental pitch of the bell sound; it does not necessarily coincide with one of the partials, and varies from person to person, but is typically around an octave below the partial called the nominal.<ref name="hibbert2008quantification"/> | ||
The frequencies of the bell partials depend on the shape and profile of the bell. By design and subsequent adjustment by removing metal, the individual partials can be tuned. The technique of tuning the partials was discovered by the Hemony brothers and Jacob van Eyck in the 17th century, lost, and rediscovered in the 19th century by Taylors bell foundry and Canon Arthur Simpson (to shorten a long story).<ref name="hibbert2021building"/> | The frequencies of the bell partials depend on the shape and profile of the bell.
