Klapa is a traditional form of a cappella singing that originates from the coastal regions of Croatia. It typically involves a group of male or female singers harmonizing together, often accompanied by clapping or simple instruments. The songs usually express themes of love, nature, and the sea, reflecting the cultural heritage of the region. This musical style is characterized by its rich vocal harmonies and emotional delivery. Klapa performances are often held at festivals, gatherings, and celebrations, making it an integral part of Croatian cultural identity. In 2012, klapa was recognized by UNESCO as an Intangible Cultural Heritage of Humanity.
