The project ”Music and Language” aimed at educating students at secondary level to be globally engaged citizens and to prepare them for the 21st Century. Learning together we wanted to develop new teaching material, review our global strategies at the schools, collaborate on continuous professional development of teachers and provide an opportunity for our students to use and evolve their 21st Century competencies in order to prepare them for a rapidly changing society. In the project, we used music as an international language as a kickstarter for intercultural exchange. The participants will be selected students from the school with a particular interest in music and their teachers from the subjects Music and English. The project took place in five phases (Explore, Curiosity, Production, Celebrate and Sense Making) which will included two mobilities. We mainly worked with rhythmic music in the Music lessons and intercultural competencies through a focus on culture and language in the English lessons. The content was structured around the three antitheses 1) Old vs. New 2) Local vs. Global and 3) Urban vs. Rural which the participants investigated together during the five phases of the project. The results of the project were gathered in a Project Presentation that showcase how schools can work with Global Citizenship and 21st Century Competencies and suggest methods and content for other teachers to use. The project was a pilot project for the participating institutions and we aim at using the results to build a long-term partnership focusing on Music and Language.
