A carillon-like instrument with fewer than 23 bells is called a chime.
American chimes usually have one to one and a half diatonic octaves. Many chimes are automated.
The first bell chime was created in 1487.[citation needed] Before 1900, chime bells typically lacked dynamic variation and the inner tuning (the mathematical balance of a bell's complex sound) required to permit the use of harmony. Since then, chime bells produced in Belgium, the Netherlands, England, and America have inner tuning and can produce fully harmonized music.[1] Some towers in England hung for full circle change ringing chime by an Ellacombe apparatus.[2]
