The Mixed Choir was formed simultaneously with the creation of the Varna Opera in 1947.

The first choirmasters were Dimitar Mladenov and Yakim Popiliev. Later, conductors Petko Mechkov, Nikola Bochev, Krastan Misirkov, Elena Pushkova and Lyubomira Aleksandrova, and Sunay Muratov worked with the ensemble.  

Along with opera performances, the Choir of the Varna Opera and Philharmonic Society participates in operettas, musicals and musical spectacles for children. The cantata and oratorio genre is also part of its repertoire. After Malina Hubcheva (1998 – 2013), conductor of the choir has been Stefan Boyadzhiev.
