The Training Course (TC) Harmony of the Sounds (HOS) was a project that involved 25 social workers, teachers, youth leaders working with young people with fewer opportunities in post conflict countries (refugees, migrants, asylum seekers). The aim of the project was to use Non Formal Education (NFE) tools, mainly the music and arts, as a fighter against racism and discrimination of other cultures. The TC was held in Fertilia – Alghero, Sardinia, Italy, March 11- 18, 2015 (Travel Days included). The following 11 countries were involved in the project: Albania, Armenia, Azerbaijan, Bulgaria, Georgia, Italy, Macedonia, Portugal, Romania, Serbia, Turkey, in total 25 participants. The working language was English. The overall aim of the project was to promote NFE methodologies for building peace through music facilitating intercultural dialogue. Through this project, we wanted to strengthen the ancient links between music and human being, proposing the use of music as a matter to promote the sense of cohesion among EU and neighboring countries (Caucasus and Balkans). This mobility project (TC) dealt with the importance of reconciliation and peace-building process stimulating the sense of solidarity and promoting the intercultural dialogue. The project focused on different topics as well as proposed the participants different methodologies that can be used in order to work on the topics of the project. The project focused on a non formal education approach based on music as a means to fight racism and discrimination of other cultures. Music is the perfect language to communicate, to live in harmony and peace. Music is a powerful tool of social change. Young people must be the leading force in the process and that’s why by doing such activities become more skilled and motivated for actions that contribute to dialogue between the conflict affected communities and peace building. Music can contribute to the establishment of a more harmonious world by joining efforts to transform reality and enhance solidarity among human beings. Music is an expressive language that allows us to communicate (both at the individual and collective levels) feelings, lived experiences and reflections about the world stemming from real life or the collective imaginary. Likewise it can increase participation. Music is a fundamental dimension of a population who is involved in a conflict because it plays an important role: it represents our identity and our roots. Music is often related to national culture because it commemorates historical and personal events like weddings or funerals and expresses feelings. The learning objective of the this project was to raise awareness on the situation of modern youngsters in post conflict countries enhancing the spirit of cooperation among EU, Balkans and Eastern Partnership countries (Armenia, Georgia, Azerbaijan) overcoming the cultural barriers which effect their lives till ages. The project represented a unique opportunity to meet professionals in the youth fields which can impact the youth lives in their countries at different levels, widening their point of views to other countries.
