In the organizer's words:

On December 6, the Tertianum Residence Berlin invites you to a special pre-Christmas tea time: The "Voice-Changers" from the children's and youth choir of the Deutsche Oper Berlin, will create a musical afternoon full of lively and festive Christmas carols from 4:30 pm. Young voices, carefully trained and full of energy, present well-known classics and new arrangements in the atrium. The entrance fee is 15 euros.

The "Voice-Changers" belong to the children's and youth choir of the Deutsche Oper Berlin. Under the direction of Rosemarie Arzt, the young male voices experience their vocal transition as a phase of musical discovery. In self-arranged pieces, supplemented by small scenic-choreographic elements, they span an arc from the Renaissance to contemporary music, making every performance a diverse experience.
