Abstract
This paper throws light on specific variant of twelve-tone technique developed by Alexander Chugaev (1924–1990), “privileged tone rows” (specific rows, derived from four transformations of single three-tone row). In the first part the original Chugaev’s algorithm for finding all such rows based on given three-tone row is explained. In the second part practical usage of that algorithm in Chugaev’s music is discussed, and individuality of composer’s usage of twelve-tone technique is formulated on examples from his music.
