Nowadays, music in Europe is a powerful tool for cohesion and unity. Festivals flourish every year, that allow European citizens to discover the neighbouring countries and to know each other by gathering around the same passion, music.The Erasmus project we are carrying out aims at highlighting the cultural diversity of Europe while diving into its popular roots. This project will involve 70 creative and talented students and 20 teachers of different subjects, music, dance, foreign languages ​​and computer sciences, from five different cultural and geographical regions of Europe, namely a French school, a Bulgarian school, a Greek school, a Romanian school and an Italian school.Between these different partners, there is a common denominator: the desire to sing a traditional musical repertoire by combining dance because traditional music has the primary function of dancing, it is an inseparable link in any European culture.But it is also the desire to work on the specificity of each language because the mother tongue gives meaning to the traditional song by its rhythm, its intonation, its accentuation, its intonation ...For a period of two years, students aged 13 to 15 will become familiar with the language and heritage of their partners' local folk music through a project website and languages teaching method ​​they will create. They will have the chance to rehearse, play and dance in authentic folk music concerts around the world as part of four learning activities in Romania, Greece, Italy and France.They will publish a final product, a DVD, containing 20 pieces of authentic music and at least 10 dances. To achieve the results of the project, in the first year students will exchange in English and will work in groups to create a simple method of teaching their mother tongue.They will subsequently have to exchange it with their foreign peers.They will work 4 types of traditional songs whose texts will be analyzed and translated; they will write articles and put copied scores online on the website created for the project.They will also make music and dance videos, so that learning from other countries will be easier. They will also learn passages from national and folk songs of their partners to be sung together.Student profiles, language teaching methods and video clips will complete the website.During this first year, an initial meeting between teachers will be held in Bulgaria, where coordinators and music teachers will meet for the first time and decide on the timeline for the first year. Romania will host its partners, teachers and students. Together, they will work on three languages ​​of the project Romanian, Greek and Bulgarian and will give their first concert with some authentic folk songs and dances.At the end of this school year there will be a mobility in Greece more specifically reserved for the exchange between the various folk dances.During the second year, local activities will involve work similar to that of the first year. A more elaborate concert will be performed in Italy as well as a final concert with all the songs and dances in France in a beautiful concert hall involving local actors. A DVD of the songs and dances will be created and the methods of languages ​​will be online and printed, to be used by all participants. It will also be an opportunity to work during workshops teaching activity on Italian and French languages ​​as these will be the next destinations during the year.CLIL will be used in the process. Europass documents will be used to recognize its results. The partners involved in the project all have strong roots with the popular dance community within their school or through groups or associations that will promote exchanges with local partners.We, the project's teachers, believe that transnational work will have many effects on all participants, both locally and internationally, especially on students and teachers, by stimulating their cooperation, their creativity, their solidarity, their confidence in themselves, their tolerance, etc ... and by encouraging the development of innovative teaching practice and encouraging openness to the world by discovering different European countries through a common musical theme. Finally, most importantly, the love of music and dance expressed in the common work of students from five different European countries will establish long lasting traditions of enjoying and sharing music together.
