The "Power of Sounds" project was a 9-day youth exchange in Rokytnice nad Jizerou, Czechia, designed around a clearly defined main objective: to facilitate the expression of emotions in a healthy and socially acceptable manner, to improve international communication competences, to enhance self-confidence, to cultivate feelings of peace and calmness, to improve the ability to focus, and to improve intercultural understanding among 40 young people from Italy, Romania, Croatia and Czechia. The objectives stem from a needs analysis conducted by the four partner organisations (Youth for Youth from Czechia, Kreaktiva from Croatia, Young Effect from Italy, and Aspire Rise Connect Inspire from Romania) with their local youth target groups. The analysis identified that young people across the four countries face common challenges: digital information overload that reduces their ability to focus, low self-confidence in developing their talents and abilities, difficulties handling stress in healthy ways, problems expressing themselves and their emotions in groups, reduced ability to cooperate effectively in person as a result of spending much of their free time online, and a decreased ability to understand others' emotions and empathise with them. To address these needs, the partners chose music therapy methods and non-formal learning as the central pedagogical approach. The intention was to give young people practical, accessible tools to manage stress and anxiety, express emotions through creative and non-verbal means, build self-esteem through small-scale performance and creative expression, and develop empathy and active listening through group musical activities. A particular focus was placed on inclusion. The project committed to including 16 participants facing fewer opportunities (40% of participants) — including those facing economic, social, geographical, cultural, educational, discrimination-related, and health barriers. The project objectives explicitly aimed to ensure these participants benefited from a safe, supportive learning environment that boosted their confidence and gave them international experience that many had not previously accessed. The project also pursued building intercultural understanding through shared cultural exchange (intercultural evenings, traditional songs and dances workshops); encouraging face-to-face interaction; developing English-language confidence in a low-pressure international environment; equipping participants with practical music-based stress-management techniques they could continue using in daily life; and creating a permanent international support network through deep friendships formed during the mobility. At a programme level, the project objectives were aligned with European priorities. The project explicitly supported European Youth Goal #5 on mental health and well-being. It contributed to horizontal priorities of the Erasmus+ programme: inclusion and diversity (through the 40% participants with fewer opportunities), green priority (through extensive sustainable practices and green travel for 3 of 4 national groups), digital dimension (through online communication tools, the project webpage, and Instagram/YouTube outputs), and the participatory dimension (through participant-led intercultural evenings, national groups led Day 6 workshops and some of the activities in Day 2 and Day 3 as described in the timetable, peer mentoring, Secret Friend method, the Social Contract activity, and participant-organised dissemination events). The project also aimed to strengthen the capacity of the 4 partner NGOs to use creative music therapy methods in their own youth work, to deepen the institutional cooperation between the 4 organisations, to disseminate the music therapy methods and exercises to local schools, and to inspire other young people in the partner countries to engage with the Erasmus+ programme — in particular by promoting the programme to local youth audiences. The plan was to leave a lasting legacy beyond the activity itself, with methods integrated also into ongoing local activities in each country and a future international project building on the same methodology already in planning.
