The Shadanga Duo is formed of flutist Katalin Szanyi and clarinetist Jason Alder. The duo focuses on the performance of contemporary works, particularly those with complex rhythms, microtonality, and extended techniques. They also work with electronics and combine theatrical elements in their performance. They began collaborating in Amsterdam in 2013, and in 2014 had 7 new commissions written for them by members of the Danish composers group Snow Mask, which were premiered in December in Aarhus. Shadanga continues to commission works for all combinations of flutes and clarinets and primarily performs works written for them. They have been invited to perform at the International Clarinet Association ClarinetFest in Madrid, the European Clarinet Festivals in Gent, Camerino, and Győr, the Havana Festival of Contemporary Music, and the Istanbul Woodwind festival. The duo appears on the album Music for Bass Clarinets on the Aural Terrains label, featuring live recordings from a concert in London’s Cafe OTO.

The name Shadanga is a Sanskrit word meaning "six limbs", and in the Karnatic music of South India refers to a structure of the tala system of time keeping. Within the context of Indian art, the six limbs of Shadanga have been translated as: Rupabheda- The knowledge of appearances; Pramanam- Correct perception, measure and structure; Bhava- Action of feelings on forms; Lavanya Yojanam- Infusion of grace, artistic representation; Sadrisyam- Similitude; Varnikabhanga- Artistic manner of using the brush and colours. These concepts also reflect the musical ideology of the Shadanga Duo.


Flutist Kata Szanyi (HU) is a music and theater maker, performer, and teacher. Her repertoire is focused on contemporary compositions for flute, alto flute and piccolo. She is a remarkable physical performer and has a special interest in making theater and complex interdisciplinary performances.

Kata finished her Bachelor and Master’s studies in the Conservatorium van Amsterdam, studying with Marieke Schneemann. Before coming to the Netherlands, she studied on an Erasmus program in Córdoba, Spain with Wendela van Swol. Her Master’s years were essential to finding her direction and approach to contemporary music-theater. Kata’s practice-based research is about the theatrical side of musicianship, reinforced through physical awareness. In addition to music performance, she has also trained as a physical performer/mime. During her research, supported by her coach and advisor Virág Dezső (Moving Academy for Performing Arts), she created music-theater pieces with the composer Felipe Ignacio Noriega and the scenographer Cinthya Oyervides. She has also premiered new compositions by Shoko Nagamachi, Louis Aguirre, Lucas Wiegerink, Wilma Pistorius, played in ensembles such as Holland Symphonia and Asko Schöenberg Ensemble, and worked with conductors Reinbert de Leeuw, Tan Dun, and Bart Schneemann. During her studies, she also attended master classes of Harrie Starreveld, Vincent Cortvrint, Marten Root (traverso), Kersten McCall, Jos Zwannenburg, András Adorján, and István Matuz.

(Bass) clarinetist Jason Alder (US) holds degrees in clarinet performance (BMus, Michigan State University- US), bass clarinet performance (BMus, Conservatorium van Amsterdam- NL), creative improvisation (MMus, Artez Conservatorium- NL), and is currently finishing a PhD in music performance (Royal Northern College of Music- UK). He specializes in contemporary music and techniques and frequently works with composers to premiere new works. He strives to bring new repertoire to the lesser-played clarinets, and has commissioned a piece for alto clarinet and alto flute for Shadanga, as well as solo pieces for contrabass clarinet. Jason has played with contemporary ensembles such as Ostravska Banda, Insomnio, Amsterdam Collage Ensemble, regularly performs with the European Clarinet Association clarinet and bass clarinet ensembles, has worked with Klangforum Wien at the Impuls Academy, and has played at many contemporary music festivals including Gaudeamus, Ultima Oslo, Havana Festival, and the International Festival for Artistic Innovation. Jason frequently works with electronics and in 2010 reconstructed Stockhausen's piece "Solo for melody instrument and feedback” (1966) to be played with only a computer performing the roles of at least 6 people that were originally required, for which this performance was written about in bass clarinet legend Harry Sparnaay's book. 

In addition to composed music, Jason performs as an improviser and is also very interested in collaborative projects, particularly those involving interdisciplinary and multimedia aspects. He often works with dancers, theatermakers, visual artists, and videographers to create new performance art. Jason has published the most detailed and thorough extended range quarter-tone fingering charts available for clarinet and bass clarinet, used by many leading players around the world.

Jason is an artist for Selmer clarinets, D’Addario reeds, Silverstein ligatures, and Behn mouthpieces.
