The Tagharan program is dedicated to the spiritual and folk branches of Armenian music. At the heart of the creation of the program is the idea of kinship of these two branches, which was first scientifically dealt with by Komitas. In the episodes of the program, we consider the relationship between Armenian folk and sacred music branches, present the stages of their historical development and their genre manifestations, describe the music component of folk and Church rites, reflect on the most important works of Church singing art as well as discuss actual problems of Armenian medieval studies and folklore with specialists.
During the first three centuries of the existence of the Armenian spiritual art of singing there were created a mass of various spiritual songs dedicated to each holiday of the Church. Starting from the 8th century, the spiritual songs for the same holiday are united in cycles consisted of eight series. Each unit of the series is called sharakan, and the whole series is called canon, karg or sark. Each canon is composed from eight different sharakans, each of which has its name. The two broadcasts of the program are dedicated to the observations of the sharakans included in the structure of canon.
