This article is dedicated to an underdeveloped, but a highly relevant aspect of work of museums, first of all, the theatrical ones, namely keeping, studying and promoting the works associated with choreographic heritage. The artistic and aesthetic potential of material and visual exhibits related to the ballet theatre is revealed. All the figurative and metaphoric world of dance involved in a particular exhibition project is considered from the standpoint of the main carrier of the theatrical idea at the level of its perception by the master of the theatrical university as a potential researcher. The proposed aspect of consideration of the monuments of choreographic heritage in the museum environment raises this problem to the quantitatively new level of conceptuality, justifies the possibility of allocating the theory of their study in an independent scientific area that integrates in the modern theatre museology as a new direction of interdisciplinary knowledge and develops through the various liberal arts.
