Starting with 30 October 2020, the series continued under the title Terzet-Trio in which the Opera Chorus and Orchestra present chamber pieces as usual. However, the artists of the Hungarian National Ballet are to be seen on stage in the upcoming months, in Swan Lake and The Nutcracker at the Erkel Theatre, and in A Streetcar Named Desire at the Eiffel art Studios.
The Opera Chorus have an indispensable role in contributing to the productions of The Muse of the French Season at the Opera, but in the live streaming it was for the first time they had prepared with French pieces. Their programme featured works by composers who are mostly renowned for their instrumental music such as Gabriel Fauré, whose Madrigal (Op. 35) and Pavana are also known in symphonic version. In the show, chorus members Éva Dunai, Judit Dévény, László Ladjánszky and Tamás Bagdi accompanied on the piano by Krisztina Andrássy-Neuenstein performed the original versions of these pieces. In Sainte Marie Madeleine (Op. 23) by Vincent D'Indy, the composer used the voices and the keyboard instruments in a unique fashion. The cantata written for female ensemble and mezzos-soprano soloist was performed by Éva Dunai, Judit Dévény, Enikő Mentes-Soós and Nadin Haris with Krisztina Andrássy-Neuenstein on the piano and Dániel Erdélyi on the harmonium.
The Opera Orchestra aimed to showcase gems from four centuries of chamber music, from Händel to Bartók. Horn Quartet in B major by German-Russian horn player and composer Friedrich Constantin Homilius (1813–1902) was performed by János Benyus, Zsolt Végh, Balázs Tóth and Gábor Kun. Béla Bartók's 44 Duos for Two Violins has a special place in the works of the composer as it was composed for practicing chamber music. In the programme, Galina Danyilova and Alexandre Dimcevski, two concertmasters of the Orchestra played a selection of their favourite movements. Jean-Baptiste Barrière (1707–1747) was the most renowned cellist of his age, who was accorded special privileges by King Louis XV to compose and teach music at his court. Sonata for Two Cellos in G major by the tragically short-lived composer was interpreted by Endre Stankowsky and János Fejérvári. The Norwegian conductor and composer Johan Halvorsen (1864–1935) wrote his Passacaglia in G minor for Violin and Viola on a theme from Harpsichord Suite in G minor by Händel, it was performed in the show by Alexandre Dimcevski and Endre Stankowsky.
The programme directed by András Aczél was hosted by Melitta Gyüdi.
