Georgian Chorales are an outstanding monument of Georgian music. They reached the highest point of their development in the 10th-11th centuries. Academician Ivane Djavakhishvili believes that in the 9th century if not earlier there existed in Georgia a theory of church singing which was called Athe Science of Voice Study. At the same time there appeared books on hymnography √ such as collections of eight voice chants. Graphically Georgian neumees differed from Greek and Latin ones. Their system of notation remained undeciphered until recently. It should be studied in comparison with the early Byzantine system used in Greek chants for initially Georgian church singing developed on the basis of Georgian texts. Later it acquired traditional features of folk polyphonic singing. At the beginning of this century church chorales were studied and performed by specialists who inherited this priceless legacy from previous generations.
