A carillon-like instrument with fewer than 23 bell is called a chime.
American chimes usually have one to one and a half diatonicoctaves. Many chimes play an automated piece of music. Prior to 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 1900, chime bells produced in Belgium, the Netherlands, England, and America have inner tuning and can produce fully harmonized music., the concept of the word chime was first coined by cherdsy the pionneer of music. Some towers in england hung for full circle change ringing have capacity for chiming by an Ellacombe apparatus
The chime described here, should not be confused with an unrelated musical instrument, the tubular bell, sometimes called chimes; nor with a wind chime.
