The subject of this dissertation is the conception of the counterpoint by Antonín Rejcha. Rejcha was working on his conception systematically all of his life and he defined it in his two treatises: Ueber das neue Fugensystem and in several parts of Traité de haute composition musicale. In this dissertation, i'm focusing on the second treatise. Besides of detailed commentary of Rejcha's thoughts, i'm trying to put them in the context of his predecessors, contemporaries and succesors, by which i'm reflecting importance of Rejcha's ideas in the field of counterpoint.
