The book is devoted to the study and identification of the musical system of Georgian church singing, which has been the subject of scientific research and discussion for decades. Based on his many years of practical experience, the author offers us the basics of Georgian choral music theory, which are mainly based on the results of a comprehensive (musicological and acoustic) analysis of the surviving sound recordings of masters of choral music.

The book consists of two parts. The first part presents the theoretical foundations of the church singing tradition, covering a wide range of issues such as the structural and compositional model of chant, modulation systems, types of cadences, types of sequences, and, most importantly, the particularly acute academic problem of mode and tuning system. The second part is devoted to the methodology of teaching oral singing, in particular, the rules of voice movement and three-voice musicianship, the peculiarities of setting different voices in three-part singing in different singing schools, etc.
