This book aims to analyze the artistic use of sound instrumentation in Vladimír Holan's poetry during the period delimited by his collections Blouznivý vějíř (Delirious Fan, 1926) and Na postupu (Advancing; 1943-48), with the latter marking the beginnings of moving away from formal verse. The text focuses on the semantic potential of instrumentation, i.e., the grouping of sounds in independent forms as a poetic tool used on the sound layer of the language.
The analysis aimed to find relevant repetitions of sounds, instrumented areas and configurations, which in Holan's poetry generally result in a semantic potential, and which must be included in the overall semantic events.
