The Weiner Chamber Choir was founded in 2018 for the National Choir Competition for Music Schools, where they won first prize. Its members are students from the Weiner Leó Secondary School of Music. In March 2022, the choir gave a highly successful concert conducted by Michael Alber (the former choral director of the Stuttgart Opera) at the Lutheran Church on Budapest's Deák Ferenc Square. This year will be their third time being invited to perform at the International Choir Festival in Ochsenhausen, Germany. Their wide repertoire ranges from Bach to György Orbán, but they also enjoy singing Hungarian folk music and spirituals.

The Musica Ludens Chamber Choir was founded in 1995 as the Kossuth Club Choir. Many of the members had already sung together in other choirs. Their current conductor is Péter Balás, a member of the Hungarian State Opera Chorus, who has been conducting the ensemble since 1997. The choir is made up purely of amateurs united by their love of singing.
They have performed several times at festivals both in Hungary and abroad, including the Festival of Blossoms in the Őrség region of western Hungary, the Budapest Choir Competition, the Riva del Garda Choir Competition in Italy, the Choir Festival in Zadar, Croatia, the Olomouc Choir Competition in the Czech Republic, the Nevers Choir Festival in France and, most recently, the Bad Ischl Choir Festival in Austria. Their repertoire ranges from a cappella Renaissance works to contemporary music.

Bat-Kol, the girls' choir of the Israel Conservatory of Music in Tel Aviv, was founded by Anat Morahg in 1984. It currently consists of about 170 schoolchildren aged 6 to 18 singing in three ensembles. The members of the choir receive a broad artistic education that includes drama and dance along with the vocal training, and they have won numerous awards at competitions. Bat-Kol frequently performs with the Israeli Opera and the Israel Philharmonic Orchestra. The choir's repertoire ranges from classical and Israeli music to folk songs from various lands and choral arrangements of pop tunes.

Prelude is actually a group of young(ish) people, half of them economists, half associate members, "greased” by an academically trained choirmaster with two degrees who has "unleashed” them on the entire choral literature, from Palestrina to Ligeti. They demonstrate their perfectionism and perseverance at their five hours of weekly rehearsals, on their joint excursions and trips abroad, at competitions, and at their concerts and recording and jam sessions.

Five singers, four albums, three ladies, two gentlemen: that's Jazzation. This Budapest-based multiple-award-winning a cappella group has already found its way into international juries' hearts at international competitions in Graz, Pinerolo, Leipzig and Aarhus, but what they feel most proud of is having shared the stage with wonderful musicians like the world-famous Bobby McFerrin and the Swedish powerhouse The Real Group. While their main focus is on jazz, Jazzation also draws on folk music from around the world, and their own compositions and virtuoso arrangements win tremendous acclaim both in Hungary and abroad. At the end of the Sunday afternoon/evening concerts in the Atrium, they will be inviting the audience of the Fourth Budapest International Choral Celebration to join along in some shared singing.
