In this MA-thesis, I investigate the usage of musical terminology in the study of modern, post-metric poetry. I present the theoretical field «musico-literary studies», and point to some examples of inconsistent vocabulary in the critical debate on musicalized poetry. I also examine the effectiveness of the musical analogy in the analysis of poetic texts, and put this to the test in three textual analyses: «Some soldier wrote» by Ursula Andkjær Olsen, «Absentia animi» by Gunnar Ekelöf and Solaris korrigert by Øyvind Rimbereid. The thesis concludes that the musical analogy and the use of a musical vocabulary should be used with some care. Although it can often highlight interesting compositional and even thematic aspects of poetic texts, the analogy only becomes fully functional when the text is structured by the same principles as the musical form in question.
