Judith de Haas is a violinist of remarkable versatility and depth, known for her transparent, warm sound, expressive musicality, and deeply communicative artistry. Her international career spans orchestral, solo, and chamber music, making her a sought-after performer across Europe and beyond. Currently based in New York City, she maintains strong artistic ties to Amsterdam and Europe.

A versatile orchestral musician, Judith performs regularly with major ensembles including the Netherlands Chamber Orchestra, Deutsche Kammerphilharmonie Bremen, and Residentie Orkest Den Haag. She previously held an Academy position with the Chamber Orchestra of Europe and has collaborated with world-renowned conductors such as Bernard Haitink, Sir Simon Rattle, Gianandrea Noseda, Vladimir Ashkenazy, Jac van Steen, Andrés Orozco-Estrada, Lorenzo Viotti, Hartmut Hänchen, Joshua Weilerstein, Reinhard Goebel, Krzysztof Urbański, and Ton Koopman. Her leadership experience as principal second violinist and concertmaster of the European Union Youth Orchestra (2012–2016) refined her artistry and orchestral insight. She has also worked with Spira Mirabilis, an innovative conductor-less chamber orchestra that explores repertoire with deep interpretative focus.

As a soloist, she made her debut at 11 years old with Mozart’s Violin Concerto No. 3 and, at 13, performed Bruch’s Violin Concerto. More recently, she was a featured soloist at Festival Musique Cordiale (France, 2019), performing Mendelssohn’s Violin Concerto. Other solo performances include Dvořák’s Romance with the Alveare Orchestra and Ravel’s Tzigane and Saint-Saëns’ Rondo Capriccioso with the Euregio Youth Orchestra.

Judith’s chamber music collaborations include performances with pianist Leonardo Reyna, Daan Boertien, Carolin Widmann, Frank Reinecke, Wolfgang Emanuel Schmidt, Silvia Simunescu, Lahav Shani, Friederike Arnholdt, and Stefano Farulli, appearing at major festivals across Europe, the United States, China, and Cuba. During the pandemic, she co-founded Wood Concerts, an initiative with pianist and duo-partner Leonardo Reyna, which sought to create intimate, interdisciplinary performances in unique venues.

She was a bi-annual participant in the Zermatt Music Festival and Academy with the Scharoun Ensemble of the Berlin Philharmonic, where she spent three weeks working intensively on chamber music and orchestral repertoire in the Swiss Alps. Since then, she has remained closely connected to the festival and has been part of its production management team for the past six years.

Her performances have brought her to some of the most prestigious venues, including Palau de la Música Catalana Barcelona, Elbphilharmonie Hamburg, Philharmonie de Paris, Philharmonie Berlin, BOZAR Brussels, Concertgebouw Amsterdam, Tonhalle Zürich, and Teatro Carlo Felice, Genoa, Palau de la Musica Valencia, Auditorium Wolkenturm Grafenegg, Teatro Comunale di Bologna, Opera de Dijon, Nationale Opera en Ballet Amsterdam, Emirates Palace Auditorium Abu Dhabi, Grand Theatre de Provence, Teatro Comunale Bolzano, and Alte Oper Frankfurt.

Judith studied violin with Carolin Widmann (Hochschule für Musik und Theater “Mendelssohn-Bartholdy” Leipzig), Michael Erxleben (Hochschule für Musik “Hanns Eisler” Berlin), Wouter Vossen (Amsterdam), and Annemieke Corstens (Tilburg) and has participated in masterclasses with Andrei Baranov, Vadim Repin, Herman Krebbers, and Christian Tetzlaff. She also holds a Master’s degree in International Management, with a focus on Art Market Management, from SRH University Berlin and École d’Art et de Culture in Paris.

Beyond music, Judith is a certified yoga teacher and has dedicated years to studying holistic body-mind health practices. Understanding that musicians are, in many ways, athletes, she is developing a coaching practice to help artists navigate the physical and mental demands of their profession, integrating movement, mindfulness, and resilience training.

In addition to her performing career, Judith has taken on significant roles in cultural management and artistic leadership, including the management for the Scharoun Ensemble Berlin (Berlin Philharmonic Orchestra), Production associate at Zermatt Music Festival, Co-Leading the concertserie at ClinkerLounge, Berlin and PR & Communication Strategist at SIRIUS Music.

With a career spanning Berlin, Leipzig, Paris, Amsterdam, and New York, Judith’s international experiences have given her a deep sensitivity to cultural differences and artistic communication. She sees music as a universal language, capable of bridging worlds, and brings this perspective into every collaboration, performance, and mentoring opportunity.
