May I ask for a certificate to use

Hello MusOpen, I am currently work on a video art project call Eroica 2020. In the video I wish to use the music from Eroica symphony. This is a commissioned work for an exhibition to celebrate the 250th birthdate of Beethoven. May I ask from Musopen a certificate to use the file from your library, please? Thank you and looking forward to hearing from you. Viet , artist from Vietnam
