The programme entitled Masquerade (referring to the word 'mask'), was a series of exclusive aria recitals by leading soloists of the Opera twice a week between September 2020 and March 2021. The one-hour programmes featured pieces compiled by the singers themselves accompanied on the piano by a répétiteur of the institute. In the 2020 episodes, stars of the recitals were mostly Chamber Singers of the institute, who were joined on stage by guest artists. From 2021, further singers appeared in joint aria recitals. The performances were hosted by Dániel Mona, Melitta Gyüdi, or general director Szilveszter Ókovács.
