Taking detours, escaping labels, conceiving of music as an exchange.
Through its artistic project, Des Équilibres aims to foster a multifaceted dialogue: between musicians from diverse backgrounds, between aesthetics, and between artistic disciplines. A variable-geometry ensemble, it was created in 2006 by violinist Agnès Pyka , who also serves as its artistic director.
Des Équilibres has remained true to this vocation of pioneering new territories without abandoning tradition: from the classical era to contemporary creation, the ensemble has tackled all forms of chamber music, but always with a predilection for rare or unpublished works.
The flexibility of its ensemble, from recital to octet depending on the programme chosen, also allows it to touch on a vast repertoire: thus, in 2018, Des Équilibres commissioned three French composers (Philippe Hersant, Nicolas Bacri and Graciane Finzi) to create three works mirroring the sonatas for violin and piano by Johannes Brahms, a project created at La Ferme du Buisson, Scène nationale de Marne-la-Vallée.
In 2021, the ensemble collaborated with two contemporary composers, Florentine Mulsant and Bryce Dessner, on two original programs, Sensibilité à la française and La classe américaine , co-produced by La Ferme du Buisson, Scène nationale de Marne-la-Vallée.
In 2024, the ensemble commissioned two creations from Claire-Mélanie Sinnhuber for the violin, cello and harp trio as part of the project ” Plucked strings, bowed strings in trio” in order to put them in comparison with two pieces by Henriette Renié, a great harpist and forgotten composer of the twentieth century.
Also in 2024, the ensemble continues its commitment to contemporary creation with the France Europe Express Magyarország program : three Hungarian composers, Máté Hollós, Gyula Bánkövi and Bence Kutrik, and three French composers, Florentine Mulsant, Édith Canat de Chizy and Claire-Mélanie Sinnhuber, resulting in a concert tour in Hungary and France.
From 2024 to 2026, the ensemble is involved in the European project Trans Europe Express , a project supported by Creative Europe, which highlights contemporary female composers. To this end, it is commissioning eight new works from French, Maltese, Hungarian and Spanish composers: Édith Canat de Chizy, Florentine Mulsant, Andrea Szigetvári, Tímea Dragony, Véronique Vella, Mariella Cassar Cordina, Anna Malek and Marian Márquez, across four countries and with ten partners.
The whole thing nonetheless pays homage to the great repertoire:
In 2022, he celebrated the bicentenary of César Franck’s birth by recreating the complete chamber music for strings in co-production with La Ferme du Buisson, scène nationale de Marne-la-Vallée, the Musée national de Port-Royal des Champs and the Musée de Grenoble. 2024 also provides the opportunity to create “In the Company of Mozart’s Favorite Instrument” during a residency at the Saint-Denis Festival, a program for violin and viola duo. This program blends classical works (Mozart, Sibelius, Spohr, Halvorsen) and contemporary works (Henri Cornilleau, Graciane Finzi, Florentine Mulsant). Encounter and confrontation are the driving force behind a rich program of enriching events for the Des Équilibres ensemble. Through a process of cross-pollinating artistic forms, the ensemble seeks to combine various disciplines with chamber music. For example, he collaborated with choreographer Michèle Anne De Mey on music by her brother Thierry De Mey in 2008. In 2009, the ensemble brought Western tradition into dialogue with the Japanese art of improvisation with Shiro Daïmon and François Rossé. The ensemble created, at the beginning of 2022, Une Nuit Transfigurée, a multidisciplinary show directed by Alain Fromager which combines music, dance, painting and video and offers a modern variation on Schoenberg’s Transfigured Night in co-production with La Ferme du Buisson – Scène nationale de Marne-la-Vallée, Le Théâtre Liberté Chateauvallon – Scène nationale de Toulon, L’ACB – Scène nationale de Bar-le-Duc and Le Théâtre des Salins – Scène nationale de Martigues. Since its creation in 2006, the Des Équilibres ensemble has established itself as a major player on the international classical music scene. Through its numerous tours and educational projects, the ensemble has shared the richness of chamber music in various countries around the world. By performing on prestigious stages and participating in renowned festivals, it has reached diverse audiences and shared its passion for musical creation and contemporary music. The musicians of Des Équilibres have traveled extensively across four continents: North America, Europe, Africa, and Asia (more than thirty destinations). These travels have given rise to artistic encounters, leading to various original projects at the crossroads of cultures and aesthetics. In 2013, the Regards Croisés sur l’Algérie project brought together the ensemble Des Équilibres and the Algerian musician Nour-Eddine Saoudi. With the Turkish pianist Fazil Say, Des Équilibres participated in the opening concert of Marseille-Provence 2013, performing Turkish and French repertoire. In 2018, the ensemble shared the stage with the Israeli Trio Atar in an exploration of contemporary Israeli music. 2022 offers the opportunity to travel to Portugal and meet the renowned Fado singer Cristina Branco in the Fado em movimento project, created as part of the 2022 France-Portugal Season. The trio, featuring Cristina Branco and Portuguese guitarist Bernardo Couto, presents a program of works by three composers: the French composer Florentine Mulsant and the Portuguese composers Fatima Fonte and Anne Victorino d’Almeida, with texts commissioned for this occasion from the writer Gonçalo M. Tavares. This project is a co-production with the Casa da Musica de Porto, the Università L’ESMAE de Porto, and La Ferme du Buisson – Scène nationale de Marne-la-Vallée. The ensemble also developed the Still Point project in collaboration with jazz pianist Ray Lema. Born in 2014, this project was revived and further developed in 2023/2024. It blends chamber music with jazz and African sounds, featuring compositions by Ray Lema for the Des Équilibres ensemble in its string quartet formation, with Lema himself at the piano. Over the years, the ensemble has developed various long-term residency partnerships: From 2018 to 2022, at La Ferme du Buisson – Scène nationale de Marne-la-Vallée In 2022 and 2023, at the National Museum of Port-Royal des Champs In 2023 and 2024, at the Théâtre de Saint-Quentin-en-Yvelines, Scène nationale In 2023, Agnès Pyka was entrusted with the artistic direction of a season of chamber music concerts at the Château de Champs-sur-Marne. In 2023 and 2024, the ensemble is also in residence at the Saint-Denis Festival. The European Trans Europe Express project will also provide an opportunity for a series of residencies until April 2026 in France, Malta, Spain and Hungary with the ten European partners of the project. In 2025 and 2026, the ensemble will also be in residence at the Liberté college in Drancy, an In Situ residence of the departmental council 93 for the educational project Jeux de cordes . As part of its long-term residencies, the ensemble implements artistic action and awareness-raising projects: After being filmed in the south of France, in 2022 the educational project Jeux de cordes, is being taken up again in the territory of Seine-et-Marne in co-production with the Ferme du Buisson, national stage of Marne-la-Vallée and the Departmental Council 77. This project, intended for middle school students in 6th grade is based on the creation of the same name by the composer Graciane Finzi. The European project Trans Europe Express will also be an opportunity for a series of educational and mediation activities (conferences, composition and performance masterclasses, workshops for young female composers, public rehearsals, post-show discussions). The ensemble also regularly participates in concerts with a social purpose, for audiences with disabilities, concerts in nursing homes, retirement homes, homes for disabled adults, young people under the supervision of the justice system, etc. Regarding his discography, it reflects the taste for discovery that characterizes the whole: In 2011, Des Équilibres recorded the world premiere of Sandor Veress’s quartets (Hungaroton); in 2013, Bartók’s 44 violin duos with the first violin of the Talich Quartet, Jan Talich (Indésens Records); in 2017, the recording Des cordes Marines with string trios by Jean Cras, Albert Roussel and Joseph-Ermend Bonnal was released (Arion Music); in 2018, Agnès Pyka and Laurent Wagschal recorded three violin sonatas by Mieczyslaw Weinberg, the first part of a complete set which was completed in 2019 with a second disc (Arion Music) with Dimitri Vassilakis to celebrate the centenary of the composer’s birth. The isolation caused by the various lockdowns is the driving force behind the recording for the Klarthe label (which becomes the reference publisher for the whole) of the three new creations by Philippe Hersant, Nicolas Bacri and Graciane Finzi of the project Brahms today , as well as Voyage around a solo violin, a journey through four centuries of music around JS Bach, A. Khachaturian and T. de Mey. In 2022, Des Équilibres recorded the complete chamber music for strings by César Franck in partnership with the Stephen Paulello studio, a four-disc set. The album Fado em Movimento , a collaboration between the Des Equilibres ensemble and Cristina Branco, was recorded in October 2023. These recordings are all unanimously celebrated by the national and international press: 5 Diapasons, FFF Télérama, Supersonic Pizzicato, 5 stars Classica, nominations for the International Classical Music Award, and finalist for the Victoires de la Musique Classique 2024 . The Des Équilibres ensemble is subsidized by the Île-de-France region and is a member of FEVIS and Scène Ensemble.
Agnès Pyka | Art Director and First Violin

A most singular and talented violinist, Agnès Pyka devoted most of her musical life to chamber music.
After studying in France and abroad with the greatest masters (Franco Gulli, Mariana Sirbu, Giuliano Carminoglia, Ferenc Rados, Lorand Fenyves…), she created Des Équilibres in 2006 , an ensemble with variable geometry and a creative laboratory of which she is first violin and artistic director.
His areas of work with Des Équilibres demonstrate his commitment to contemporary creation:
In 2018, she commissioned three works from the three composers Nicolas Bacri, Philippe Hersant and Graciane Finzi, echoing the triptych of Brahms sonatas, a project created at La Ferme du Buisson – scène nationale de Marne-la-Vallée.
In 2021, she collaborated with two contemporary composers, Florentine Mulsant and Bryce Dessner, on two original programs, Sensibilité à la française and La classe américaine , co-produced by La Ferme du Buisson, scène nationale de Marne-la-Vallée.
In 2024, she created the project Plucked Strings, Bowed Strings in Trio for which she commissioned two creations from Claire-Mélanie Sinnhuber for the trio formation of violin, cello and harp in order to put them in comparison with two pieces by Henriette Renié, a great harpist and forgotten composer of the twentieth century.
Also in 2024, she continues her commitment to contemporary creation with the France Europe Express Magyarország program : three Hungarian composers, Máté Hollós, Gyula Bánkövi and Bence Kutrik, and three French composers, Florentine Mulsant, Édith Canat de Chizy and Claire-Mélanie Sinnhuber, resulting in a concert tour in Hungary and France.
She is the originator of the European project Trans Europe Express , a project supported by Creative Europe, which highlights contemporary female creation with a series of events from 2024 to 2026.
