Except for the small detail that it isn't true. In change ringing, what you do is to cycle through some subset of the permutations of N bells. So you might begin 123456 123465 124365 and so on. The whole thing is made up of blocks of N bells in each of which each bell is rung once. Therefore, all bells have (on average) the same period: one ring, on average, out of every N.
The bells are hung in such a way that they naturally want to swing with equal periods, so you don't have to disturb one too much to make it ring one place earlier or later in the cycle. (A bell is never moved by more than two places.)
I don't see any reason why a peal of bells couldn't be set up to produce the effect jws described, but it wouldn't be at all the same thing as change ringing.
