Campanology is the study of bells and the methods of casting, tuning and sounding them, of the creation and perfection of musical instruments consisting of one or more racks of bells and the composing for and playing on these.
The origin of the word campanology is from the latin campana meaning bell and logia meaning to study.
The instrument is played sitting on a bench by hitting the top keyboard that allows expression through variation of touch, with the underside of the half-clenched fists, and the bottom keyboard with the feet, since the lower notes in particular require more physical strength than an organ, the latter not attaining the tonal range of the better carillons: for some of these, their bell producing the lowest tone, the 'bourdon', may weigh well over 8 tonnes; other fine ones settle for 5 to 6 tonnes. A carillon renders at least two octaves for which it needs 23 bells, though the finest have 47 to 56 bells or extravagantly even more, arranged in chromatic sequence, so tuned as to produce concordant harmony when many bells are sounded together.
The oldest are found in church towers in continental northern Europe, especially in cathedral towers in northern France and Belgium, where some (like the St. Rumbolds Tower in Mechelen, the Cathedral of Our Lady in Antwerp) became UNESCO World Heritage Sites – classified, rather misleadingly, with the Belfry of Bruges and its municipal Carillon under 'Belfries of Belgium and France'.
The carillon of Kirk in the Hills, Bloomfield Hills, Michigan, United States, has the highest number of bells in the world: 77.
Modern large carillon edifices have been erected as stand-alone instruments across the world, for instance the Netherlands Carillon at Arlington National Cemetery.
The here described chimes, often singular chime, should not be confounded with another musical instrument called chimes or tubular bells.
The most common type is still change ringing, at which the order of the bells' strikes changes sequence after sequence without repeating any previous order. Each of the many different ways this can be done, is known as a "method". A very simple example is that of the plain hunt method, here shown for 5, 4 and 3 bells: 12345 1234 123 21435 2143 213 24153 2413 231 42513 4231 321 45231 4321 312 54321 3412 132 53412 3142 (123) 35142 1342 31524 (1234) 13254 (12345) A complete set of sequences or 'peal', for 4 bells needs nearly half a minute for its 4! (4x3x2x1=24) 'changes' of four strikes, for twelve bells the 12! changes of twelve strikes would last half a lifetime. A seven bell peal is not so uncommon and takes about three hours. In the above table, the three bells sample is a peal: 3! (3x2x1=6) changes of 3 strikes, each of the others is just a 'touch' or incomplete set of permutations.
The hobby spread to a few other countries as well, as shown by the Australian and New Zealand Association of Bellringers (ANZAB) – About Bellringing.
