Stage musicals stand out for their multimodal nature, and thus convey meaning through verbal, audio and visual semiotic resources. So far, studies on the translation of musicals have focused mainly on lyrics, without taking into consideration their multimodal nature; when the topic of the multimodality of songs has been researched, it was mostly in popular music and opera. When it comes to stage musicals and their translation, it is evident that there is a lack of substantial research on how meaning is expressed through interaction between modes. However, due to their nature, stage musicals require a multimodal translation approach. To tackle this, the paper presents a model of analysis that considers the semiotic complexity of these songs and demonstrates how they use verbal, audio and visual resources to further the plot. This model was applied to the musical Hamilton (2015) to understand the role of multimodality in a modern stage musical and to address the question on how to tackle its translation.
