The Mathematics of Bell Ringing

This lecture will look at change ringing, which is ringing a series of tuned bells (as you might find in the bell tower of a church) in a particular sequence, and this has exciting mathematical properties.
We will also ask: why are bells bell-shaped? What properties of this shape create the sound of a bell, and by what amount should we scale the size of a bell to produce changes in pitch?
