The festival is open to any French or foreign musical ensemble. Most participants are students at a university or music academy/school. But any amateur band may take part.

Among the 672 music groups that have submitted their application to play at the Belfort FIMU 2017, about a hundred has been selected. A record for this 31th edition! The quality, the consistency and the originality of their artistic proposal allowed the jury members of the selection committees to decide between them. The professionals, the teachers and the students paid particular attention that all the musical styles are represented: classical, jazz, various, world music, modern music and new music.

From China to Mexico, through Burkina Faso and Netherlands, the 1600 musicians expected during the Pentecost weekend represent 32 different nations, thereby demonstrating that the Belfort FIMU deserves more than ever the qualifier “international”. The festival will hold high the values of its triptych: diversity, gratuitousness and friendliness!
