Resumen: The following Final Degree Project presents a teaching unit of English and music subjects using the CLIL (Content and Language Integrated Learning) methodology, with different activities and materials. This project tries to be a good example of how to develop a didactic proposal with this methodology, since it is not easy to do it and many times important points that must be detailed and explained in it are forgotten. Thus, this project gives the keys to develop the CLIL methodology correctly, with a very well-structured teaching unit that serves as an example for teachers that want to know how to do it, based on a theoretical framework that will help to understand better this methodology.
