The eTwinning project "Cultural Harmonies" aims to promote the sharing and appreciation of the musical richness found in traditional instruments from different countries. Students will have the opportunity to delve into musical traditions by exploring the characteristic instruments of each culture. Throughout the project, participants will research, share, and learn about the traditional instruments of their own country and partner countries, highlighting the uniqueness and cultural significance of each. The exchange of experiences will be facilitated through online platforms, promoting intercultural understanding and strengthening bonds between students. Activities will include digital presentations, videos, and even the possibility of creating collaborative music, providing a complete immersion into the world of traditional sounds. The ultimate goal is not only to enrich students' musical knowledge but also to promote cultural diversity and unity among different musical traditions worldwide.
