Problems of reconstruction of music of the 18th century (using the example of the chant "Angel Vopiyashe")

The article deals with an unknown manuscript of the late 18th century found in the archives of the Dmitrov Kremlin. Notes previously belonged to the Apraksin family and were kept in the library of the Olgovo estate. Stepan Stepanovich Apraksin was a well-known music lover, in Olgov there was a serf theater, an orchestra, and a choir. The singers sang at divine services in the Church of the Introduction of the Virgin in the village adjacent to the estate. The manuscript contains two hymns — "Dostojno est’" and "Angel vopijashe". The manuscript contains an indication of the authorship of Bortnyansky. The question is being considered whether this authorship can be attributed to both chants, or only to “Dostojno est’”. The music of the choir "Angel vopijashe" is analyzed.The chant "Angel vopijashe" most likely belongs to early classicism, it can be dated to the 1780s. It was not written by the most skillful author, who composed it on the model of Bortnyansky's chants.
