Statement of the problem. The bandura art is an integral part of Ukrainian musical culture. Gender asymmetry is clearly noticeable in the process of its formation and development: for many centuries, the bandura playing was considered a “non-female” thing. However, the leveling of this asymmetry during the 20th century opened up new, gender-independent perspectives for this ancient art form. Among the well-known Ukrainian female bandura players of our time is Lubov Mandziuk – PhD in Art Studies, Associate Professor of the Folk Instruments of Ukraine Department at the Kharkiv I. P. Kotlyarevsky National University of Arts. Her contribution to the establishment and confirmation of modern bandura art in Kharkiv region and Ukraine in whole is determinative. Recent research and publications. Lubov Mandziuk’s artistic activity found coverage in the scientific investigations of О. Bobechko (2014), І. Lisniak (2019), S. Nikolenko (2021), І. Panasiuk (2002), Т. Sliusarenko (2015; 2018). However, the scientists only fragmentarily elucidate the considerable musicological achievements of the artist. Objectives, methods, and novelty of the research.
