I spent a while learning English change ringing, on specially mounted church bells. It is basically an exercise in combinatorics: the "change" is applying the pattern so that the bells ring through all possible sequences that the pattern can do. At first it sounds like noise, but after a couple of years, you do start to notice a certain musicality to it. As I understand Schoenberg, one of his ideas was that you cannot re-use a note until all the others have been used, which is essentially the same requirement that change ringing has. (The bells are heavy and are swinging through their full arc, so you cannot change their order very quickly.) After realizing this, I listened to some Schoenberg and found it much more listenable than I did in college.
