Klapa singing is traditional part-singing homophonous singing not accompanied by instruments. A phenomenon of klapa singing is a continuous and relatively old. In this form is known from the mid of 19th century, when cultural and musical identities of small Mediterranean cities along our coast and on islands were trying to become distinctive, particularly in Dalmatia. Melody in a song is always in third, accompanied by the second part whilst the third part’s role is to complement the chord. Since 2012 Klapa singing is inserted to the UNESCO list of World Intangible Cultural Heritage. There are three klapa groups active in Supetar – men klapa “Vala”, active for more than 30 years and two women groups – “Alegrija” and “Pupe”. Performances of Supetar klapas can be seen during the Supetar Summer (Supetarsko lito) within which are organized klapa evenings on Thursdays.
