A suggestion from Ramon, one of my teachers/tutors,
Merlijn Twaalfhoven is a dutch composer and musician who has done some projects which were aimed at breaking down the barriers put up between communities, physical or not, through the playing of music. He creates a dialogue between the communities who are at odds, or divided from each other, by uniting them with that one thing we all love: Music.
Cypriots from North and South
Bridging Music and People from the West and Middle East
Music in a refugee camp in Syria
Music to cross the segregation wall in Bethlehem
What I can conclude from these examples, which I could use in my project, is
the use of art, such as music, or another common interest, to break the barriers between communities and/or establish links between them.
