This article is dedicated to definition of structural organization of musical ekphrastic discourse. In the process of the analysis of Ian McEwan’s novel “Amsterdam” fourteen ekphrastic descriptions were singled out. They are based on common frame and macroposition. At the same time each ekphrastic phrase represents a set of local themes included in macrostructure and connected either with creating or performing a symphony. The presence of vertical and horizontal connections ensures the cohesion of discourse. Separate ekphrastic phrases are united by common structural pattern, the major features of which are the presence of descriptive and interpretative parts, linearity, metaphorical and associative character.
