The Republic of Croatia has an extremely rich cultural heritage, both tangible and intangible. In 2012, UNESCO included “klapa way of singing” as an intangible cultural asset on the list of world cultural heritage protection. Original “klapa” singing is a cappella singing without the accompaniment of instruments. It originated from traditional folk singing that developed over centuries in the area of Dalmatia. When we talk about “klapa singing”, we can say that it is a very young musical entity that began its story in 1967 with the appearance of the Dalmatian klapa Festival in Omiš. Everything that came before can be called the forerunner of “klapa singing”. Today there are over 800 “klapa” in Croatia, “klapa” have become commercialized, and there is a great danger that the original “klapa way of singing” will lose its importance and direction of development. There are “klapa” that sing exclusively a cappella, there are those that use instruments in addition to the original singing, and there are also modern “klapa” that perform exclusively with the accompaniment of instruments. Also, “klapa” that sing to the accompaniment of traditional instruments such as mandolins and guitars differ significantly from those that use electric instruments, drums etc. The protection and promotion of original “klapa way of singing” is extremely important for the survival of this intangible cultural asset.
