The kolijani-koleda event on Krk, which takes place in the Christmas and New Year period, is marked by processions moving from house to house expressing good wishes, together with a choosing-the-king custom. Through changes and innovations this ritual has ensured its firm entrenchment in the consciousness of the people.
The symbolic presentation of village unity moves from the secular to the religious sphere; their mutual permeation is constant and inseparable, and the performance of the ritual is the present expression of collective identity and feelings. The dialectical relationship between tradition and revival is confirmed in the interweaving of the old pre-Christian symbols (although they are expressed with new meaning or just repeated as a rule) with the most contemporary expressions of identity.
This according to “The kolijani ritual event on the island of Krk, Croatia: Continuity or revival?” by Tvrtko Zebec (Yearbook for traditional music XXXVIII  pp. 97–107). This issue of Yearbook for traditional music, along with many others, is covered in our new RILM Abstracts of Music Literature with Full Text collection.
