Popular and multimodal forms of cultural products are becoming increasingly visible within translation studies research. Interest in translation and music, however, has so far been relatively limited, mainly because translation of musical material has been considered somewhat outside the limits of translation studies, as traditionally conceived. Difficulties associated with issues such as the 'musicality' of lyrics, the fuzzy boundaries between translation, adaptation and rewriting, and the pervasiveness of covert or unacknowledged translations of musical elements in a variety of settings have generally limited the research in this area to overt and canonized translations such as those done for the opera.
