The event will also mark 20 years since the entry into force of the Convention for the Safeguarding of the Intangible Cultural Heritage in Croatia.
The Istrian scale is a type of two-part singing specific to Istria and the Kvarner region of the northern Croatian Adriatic, including the islands of Krk and Cres. Its inscription on the UNESCO list in 2009 was partly thanks to the Association of Sopile Players of the Island of Krk.
The association was established in 1988 to bring together sopile players and music lovers to safeguard and promote local traditional music. It has between 100 and 150 members.
