This discourse linguistic short paper focuses on the heuristic concept of discourse poetics within a discourse linguistic framework. The goal is to integrate poetological considerations related to the concept of poeticity into the context of linguistic discourse analysis. From this standpoint, it explores the concept of poetics of knowledge, emphasizing the correlation between the specifics of linguistic expression and the epistemic objects they may refer to. Building upon this, discourse poetics that functions as a discourse linguistic epistemology is characterized by its focus on the poetic function of language use corresponding to the category of poeticity as a linguistic marker within discourse. It is assumed that linguistic phenomena falling under this category, can be observed and interpreted transtextually, using corpus pragmatic and hermeneutic approaches. This is illustrated by examples taken from the analysis of music discourses based on a corpus of 13,499 contemporary music reviews, previously presented by the author.
