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.
The program is dedicated to one of the highly artistic examples of Armenian sacred music, to the sharakan (hymn) Khorhurd Khorin (O Mystery Deep) authored by Khachatur Taronatsi, 12th-13th century famous poet and musician, abbot of the Monastery of Haghartsin. This sharakan is the only hymn from this author's legacy that has survived to this day with its melody.
