The Rudolf Matz International String Competition is a respectable musical event held biennially with participants from all over the world and internationally most prominent musicians and music pedagogues as members of the jury.

This competition, unique in the world made its popularity thanks to specific propositions – it is the only competition in Croatia, which is intended for violinists, violists,  cellists and double bass players who are competing in the same category, whereby the emphasis is placed primarily in evaluating the quality of performance, music and talent, rather than on specific technical skills on each instrument as in other competitions. Another specificity is that there are no age categories – it is categorized by the years of learning the instrument.
