Bell chiming is a Slovenian folk music tradition involving performers playing tunes on church bells by holding the clapper and striking the rim of a stationary bell. The tunes played consist of repeated rhythmic patterns into which various changes are included. Because the sounds of bells are inh...
متن کاملBells, Motels and Permutation Groups
