From 1678 until his loss of life Diletsky lived in Moscow. Ahead of this he resided in the Ukraine, examined in Poland and briefly resided in Smolensk. Being a composer and musicographer Diletsky composed a treatise entitled “Musikiskaya Grammatika” which illustrated a good deal about Russian music. In the torso of the task he defined: 1. The rigorous formulas for deriving a polyphonic piece from imitated lines. 2. Contrasting music which included an ensemble or orchestra performed against an individual instrument or little group of equipment. Of special curiosity was Diletsky’s illustration of the ideas using the music from the leading Polish composers.
