Natalia Kotarba is a Polish violinist born in Krakow and currently based in Brussels. She is one of the founders of the Karski Quartet. Natalia holds a Master Cum Laude from the Academy of Music in Krakow, the Royal Northern College of Music, and the Royal Conservatory in Brussels, where she pursued her Artist Diploma under the guidance of Philippe Graffin. From 2019 to 2022, she continued her training as a string quartet artist-in-residence at the Chapelle Musicale Reine Elisabeth in Belgium, receiving the artist diploma and remaining as an associated artist.

Natalia enthusiastically embraces a wide range of musical genres. She has collaborated with Jean-Claude Vanden Eynden, Philippe Graffin, Gordan Nikolic, Krzysztof Penderecki, and the Oxalys Ensemble. She has performed at music festivals such as Midis-Minimes, Festival Résonances, and Ysaye’s Knokke in Belgium, as well as the Festival Pablo Casals in Prades, France, and the Istanbul Music Festival in Turkey. In 2018, she had the honour of performing at Bozar in the presence of the Belgian and Dutch monarchs during the 60th-anniversary celebration of the Benelux.

Natalia is a laureate of the Chopin Foundation’s prize for outstanding students (2017). Alongside the Karski Quartet, she was awarded a Grand Prix at the International Chamber Music Competition Triomphe de L’Art in Brussels (2018). More recently, the quartet became a laureate of the Christine and David Anderson Career Development Prize at the 2022 Banff International String Quartet Competition.

Most recently, in May 2023, The Karski Quartet recorded a CD of Boccherini’s lesser-known string quintets, including some premieres, with cellist Raphaël Feye. The launch concert for this recording is scheduled for April 2024 at Flagey. Throughout the 2023/2024 season, the quartet will continue to be a part of string quartet networks such as Le Dimore del Quartetto, Merita Platform, and the Amsterdam String Quartet Biennale.

As of 2019, Natalia is a member of the orchestra Les Métamorphoses under the direction of Raphael Feye, and of the Ensemble K under the direction of Simone Menezes.

Natalia had the pleasure of performing at the “Conference on the Future of Europe” in the presence of French President Emmanuel Macron, Ursula Von der Leyen, and David Sassoli. Together with her sister, she had the honour of performing at the House of Representatives in Brussels, in the presence of Ukrainian President Volodymyr Zelensky and Prime Minister Alexander de Croo.

Natalia was strongly influenced by the jazz improvisation classes of the famous Polish jazzman Jarosław Śmietana. She believes in the importance of remaining open to different styles and types of music, which helps her produce personal and honest interpretations of works. Additionally, she is a dedicated teacher and a great enthusiast of music education projects that introduce children and young adults to the beautiful world of music. For the past two years, she has been teaching at the Summer Masterclasses for young musicians in Oslo.

Thanks to a loan from the King Baudouin Foundation and Strings For Talent, Natalia currently plays a violin made in 2020 by Nicolas Gilles (France) (

In 1988 he participated in the television programme “L’école des Fans”, a classical guitar special presented by Jacques Martin with Pedro Ibanez as guest. The same year he won first prize at the international classical guitar competition in Romans (Isère).
