Abstract
The article presents a structural analysis of the dynamics of the development of the prima-kobyz instrument, alongside methodological advancements. The aim of the research is to identify the distinctive features of the evolution of playing techniques on the prima-kobyz. The research tasks included studying the program for teaching the prima-kobyz and structuring the development of the school for playing this instrument by analyzing performance data and employing performance analysis methods to gain a comprehensive understanding of the history and development of performance technique. The result of this research is a synthesis of performance analysis, demonstrating the main trends in the development of this national instrument. The comparative analysis allowed to identify characteristic features of the dynamics of development of modern performance techniques. The peculiarity of performance style has been disclosed and analyzed. Clear examples of research illustrating the development of performance technique are presented. The main conclusions of the research are that although the school for playing the prima-kobyz borrowed violin playing techniques and cello bowing techniques, while adapting national compositions and techniques of various string instruments, it has achieved the status of a national instrument. This study represents promising material for further investigation into the development of the national instrument.
