Between the Visual and the Acoustic. On auditive adaptations of experimental texts in a German-Czech context
the Czech-German context. On the one hand, visual and phonic poetry represent distinct and separate fields, but on the other hand, there are many intersections: visual compositions can be multisensory and evoke acoustic se...
