This article is the result of a scrupulous investigation of a conceptual issue of the methodology for studying the verbal text of a rock composition as an element of a synthetic text. Based on the well-established idea in the research community about the need to create / use interdisciplinary methods to analyze the verbal subtext of a rock composition, the authors of this study have tried to include the category of image in the methodology of the philological analysis of the verbal component. As a result of the study, the authors conclude that the required structural elements of the verbal component of a rock composition, which distinguish it from both non-synthetic and other synthetic texts, are the phonic level and the subject organization. Considering the subject organization as the central category of not only the verbal subtext of a rock composition, but also of rock and roll discourse in general, the authors introduce and use the term “image character” in the analysis of E. Letov’s work, which allows them to move away from the traditional classification of lyrical subjects and to reveal the links between the lyrical subject of lyrics and the hero of the biographical myth created by the rock poet. The second significant achievement reported in this article is the identification and perception of the phonic level of the verbal text of a rock composition as a marker that distinguishes its text of a traditional, “printed” poem. It is not by chance that all observations made by the authors regarding the phonic organization of lyrics have turned out to be valuable. It was important for the authors not so much as to show the difference between lyrics and a poem (although it was important too), but rather to demonstrate the adherence to principles even in the formal structures of a performing supertext.
