The article shows an analysis of text’s units with the semantics “city” as an element of textual semantic field “patriotism”. The authors analyzed the corpus of the Russian song texts of the 19th-20th centuries. The analysis revealed the textual units with semantics “city”, which actualize the patriotic semantic in the context. It also showed that the majority of units consist of toponyms. According to the results of the study, the authors concluded that these textual units acquire additional incremental patriotic semantics in the song context. The authors proposed methods for studying the lexical level of a song text by constructing a text semantic field. The article is addressed to specialists in the field of philology and related fields of humanitary knowledge.
