In 2017, the initiative took place in Rome at the Basilica of S. Maria in Aracoeli and in Tehran, Iran, at the Vahdat Hall of the Roudaki Foundation, in collaboration with prominent institutions such as the Conservatory of Music S. Cecilia, the University Sapienza, and the Department of Music of the Ministry of Culture and the Islamic Republic of Iran. It received strong support from the Ministry of Foreign Affairs and International Cooperation and the Pontifical Council for Culture right from the start. In 2022 and 2023, the project was hosted at the Sanctuary of Greccio and in Rome at the Basilica of S. Paolo Fuori le Mura as part of the Suoni per Roma event.
