The HEM works together with many international institutions in the field of teaching and culture. Its partners are in Europe, the Americas and Asia. It has many students from other countries, and organises exchanges of students and teachers with other music institutions.

Teaching and artistic projects are also carried out in partnership with other institutions to encourage exchanges with non-European traditional cultures.

International institutions with which the "Haute école de musique Genève – Neuchâtel" regularly works include the Edward Said National Conservatory of Music in Jerusalem, the Fundación del Estado para el Sistema de las Orquestas Juveniles e Infantiles de Venezuela, the Núcleos Estaduais de Orquestras Juvenis e Infantis da Bahia (NEOJIBA) in Brazil, the Kunitachi College of Music in Japan and the Shanghai Conservatory of Music.
