Change ringing with the bells ringing in sequence (as is traditionally done) is inefficient: a De Bruijn sequence can accomplish all permutations faster.
Instead of one bell at a time, ringing them as chords allows hearing every possible mixing. Every possible n-chord sequence also seems doable for small n.
Neither of these work so well with the physical constraints on how often a single bell can be rung. Both long gaps and rapid succession are bad.
