Research Retreats
Where visual art becomes sound — for cellists and composers
A collaborative masterclass shaping contemporary sound
Draw inspiration from visual art and develop new work together towards a public performance.
Research Retreats — where music meets fine art
Research Retreats revolve around an exhibition at Dat Bolwerck, a vibrant centre for contemporary art. This unique setting creates an intensive space where music and fine art enter into dialogue.
Over four immersive days, cellists and composers work closely together, guided by experienced mentors. Through focused collaboration and reflection, participants refine their work towards a shared outcome.
The retreat culminates in a public Research Performance, where artists present their work and bring the exhibition to life through sound.

Cellists — Developing your artistic voice
Work on both your own repertoire and newly composed works by the participating composers.
Through masterclasses, you develop your artistic projects further, with or without piano accompaniment.
Working intensively with contemporary repertoire encourages you to take new steps in your musical practice, contributing to your growth as an artist and the development of your unique musical voice.
Cellists
We start in advance with an online meeting with the visual artist in which all students and teachers participate. We learn more about the theme and the ideas of the artist and discuss the direction, including further development of the project.
Cello students will practice the compositions/sketches of the composers in advance. To support this, we are organizing 1 online meeting with Jeroen den Herder. Furthermore cellists bring their own repertoire to the Research Retreat. As part of your preparation for the course, we ask you to select two compositions by Alfian Emir Adytia to study in advance.
Composers — Composing in dialogue with visual art
Explore the background of the exhibition together with the artist, and shape your experiences, thoughts and interpretations into contemporary sound.
You then share your work with the participating cellists. Working closely with the musicians in Zutphen often leads to unexpected insights, with continuous support from the teachers.
After the retreat, you receive a video recording of your composition.
Composers may also participate online — we ensure a strong and reliable connection.
Composers
We start in advance with an online meeting with the visual artist in which all students and teachers participate. We learn more about the theme and the ideas of the artist and discuss the direction, including further development of the project.
Composition students start to create one or more compositions (or sketches) after this meeting, drawing inspiration from the exhibition. Each composition should be approximately 7 minutes in length and can be written for 1 to 5 cellos, with or without piano accompaniment. The compositions (or sketches) will be reviewed with the teachers in 3 online meetings. The pieces will be shared in advance with the participating cellists, whether or not in a rough form. These pieces will be tested, refined, and completed during the retreat.

LIFE-LINE – BACK TO THE SOURCE
Karin Bos (1966, NL) graduated at the Amsterdam School of Fine Arts in 1989. She works as a visual artist in Amsterdam, the Netherlands. Her main media are painting, drawing and printing.
People are the focus point of her work. Main characters are usually girls or women. Especially mutual relative power and relations have her interest. Frictions and inequality in these relationships is a recurrent theme. For instance between man and woman, or adult and child, or children amongst each other, group behaviour versus the loner. When the pursuit of harmony fails, it becomes interesting for her work.
‘LIFE-LINE – BACK TO THE SOURCE is a show about loss. For this project the artist went back to the source and followed the water of her childhood at the IJsselmeer lake. The result is a poetical show in which loss, grief, hope, resilience and water meet in an installation combined with new paintings and works on paper.

The Research Process
Exploring the exhibition
We explore how the exhibition personally moves and inspires you. We meet the artist – after which the creative process begins.
SHAPING SOUNDS
Experiences, thoughts, and interpretations are shaped into sound. Sometimes a clear idea emerges quickly, while at other times more time and experimentation are required. Throughout this journey, the teachers are there to support you.
THE CHALLENGE FOR THE CELLISTS
Before traveling to Zutphen, you will receive the new compositions, allowing you to familiarize yourself with these fresh sounds. Additionally, you will prepare repertoire of your own choice, which you will work on during the masterclasses.
CELLISTS AND COMPOSERS COLLABORATE
The first encounter with the new music often brings surprising insights. Experimental works can be particularly stimulating, while other compositions may feel instantly familiar, as though they are already part of your repertoire.
As rehearsals progress, a stronger connection with the composers’ vision often develops, leading to an enriching exchange of ideas. At times, technical precision is required to translate ideas into sound, while at other moments, the input of the musicians elevates the compositions to a higher level.
The teachers are ready to coach and guide you. An open attitude is encouraged, along with learning from each other and taking new steps in the musical process. All of this contributes to your growth as an artist and helps you discover your unique musical voice.
TEACHING TEAM
Jeroen den Herder
Jeroen den Herder completed his studies with distinction with Maria Hol, Dmitri Ferschtman and Christopher Bunting. He then became a leader of the Cello Octet Conjunto Ibérico, a group with a worldwide reputation as a full time cello ensemble.
Den Herder gained several music awards. Among them a first prize-winner of the “Postbank Sweelinck” cello competition and the first prize of the Foundation of the Royal Concertgebouw Amsterdam. He’s been an active chamber music player, performing with musicians like Janine Jansen, Igor Roma, Anner Bijlsma and as a member of the Ruysdael Quartet Den Herder performed in all major concert halls in Holland (Concertgebouw) England (Wigmore Hall) and Japan (Oji Hall). Their concerts at the Amsterdam Quartet Biënnale received much acclaim. Between 1999 and 2012 Jeroen has been the cellist of the Nieuw Ensemble, one of the leading Dutch ensembles for contemporary music.
Fulfilling the function of artistic director CelloWercken Zutphen, which embodies both the International Cello Festival and the Cello Academy, he commissioned contemporary composers the write for the festival, leading to inspired projects such as The Tibetan Book of the Death and Passion of Innocence.
Den Herder has been a dedicated teacher ever since he took a professorship at the age of 22 at the Utrecht conservatory. His lessons are based on the development between mind and body, and a cello technique inspired by his teacher Christopher Bunting, a former student of Pablo Casals. Cello playing based on natural principles like gravity, character and playfulness.
“Everything is music, play not to avoid mistakes, delegation of body functions and breathing” are some key topics which will lead to a healthy way achieving perfection. His main focus is making people aware what they exactly practise. He believes being aware of one’s imagination, sensitive listening, intuition and delegation of body functions are elements that have proved to be the best teachers for life.
He’s been a regular guest teacher at the Conservatory in Minsk (2003-2010) and visiting guest- professor at the University in Tainan, Taiwan. Furthermore he has given masterclasses in Holland, Belgium, Spain, Germany, France, China and Israel. Today he helds positions as a teacher at the Conservatories of Utrecht and Rotterdam.
“I’ve heard Jeroen den Herder performing the Elgar cello concerto with the Sint Petersburg Philharmonic Orchestra. He played with great distinction and sensitivity, and I believe he will grow into a wonderful cellist” Yehudi Menuhin, 1995.
Vanessa Lann
Vanessa Lann is a Dutch-American composer, pianist and educator living and working in the Netherlands. Born in Brooklyn, she began studying piano at the age of five. Her first compositions also stem from her childhood years.
After graduating from Harvard University she came to the Netherlands in 1990 to continue her studies in composition with Theo Loevendie and Louis Andriessen at The Hague’s Royal Conservatory.
Shortly after arriving in the Netherlands she received her first commission from ensemble Orkest De Ereprijs and has continued to write for Dutch and international musicians, ensembles and festivals ever since.
She now has a total of 95 commissioned works to her name, ranging from solo pieces to works for large ensemble, choir, and orchestra. She has also worked on a number of scenic and staged projects with a range of interdisciplinary collaborators.
In 2022 Vanessa Lann was appointed as the first Head of Composition for Film and Theatre at the ArtEZ Conservatory in Arnhem. In this part-time position she leads an international team of academic staff and visiting professionals from the film and music sectors to provide a dynamic, practically-based curriculum designed to equip students for future careers in composing for film and the live performing arts.
Arnold Marinissen
Arnold Marinissen: ‘For me, creating music is all about immersing. Warmth and pulse are words that come to mind when I try to describe my music. Voice and text are important; I like to follow the route that a text lays out for me, to deal with breath, diction, nuances of intonation, and I’m intrigued by the personality of each individual voice.’
With his background in percussion he also likes to write for this multi-coloured family of instruments. But he equally gladly dedicates himself to strings, winds and keyboards, electro-acoustic music and music for dance and film.
His works were performed by, amongst others, Residence Orchestra string trio, Asko|Schoenberg Ensemble, Storioni Trio, Slagwerk Den Haag, Silbersee, Calefax Reed Quintet, Ensemble SCALA, Ensemble Variances (France), Maat Saxophone Quartet, Asko Kamerkoor, Pinquins Percussion Trio, Prisma Strijktrio, and performers such as Katharina Gross (cello), Helena Rasker (voice), Michel Marang (clarinet), Goska Isphording (harpsichord), Ernestine Stoop (harp), Claire Edwardes (percussion), Tatiana Koleva (percussion), Raymond Honing (flute). He created work for choreographer/dancer Ederson Rodrigues Xavier, for the Dutch cinema film Bernard, and for an audio visual installation by the Italian artist Pierluigi Pompei.
His vocal quintet Von Pferden, Gräsern, Sonnen, Menschen was nominated for the Toonzetters Best Dutch Work of 2012 Prize. It was performed by VOCAALLAB in the Holland Festival 2012, and by EXAUDI in the UK. His work has been performed throughout the Netherlands, in the Biennale di Venezia, the Huddersfield Contemporary Music Festival, the PASIC and Zeltsman Marimba Festival (USA), Sao Paolo (Brazil), Taipei (Taiwan), Zagreb (Croatia) and Wellington (New Zealand), amongst others.
His music also sounded in the Dutch cinema film Bernard and in dance productions by Club Guy & Roni, Korzo Productions and Scapino Ballet; it was broadcast by the BBC and in The Netherlands.

Arjan Linker
“Incredibly versatile, deeply devoted to music, overwhelming, and an excellent trombonist” – Jury of the Grachtenfestival Award
Arjan Linker (2000) is a Dutch composer and trombonist, specialising in North Indian Classical music. Coming from a background in classical music and a widespread interest he developed himself into a versatile musician working as a composer, trombonist, arranger and improviser in a variety of projects. His music reminds of impressionism, minimal music and early baroque, as well as hip-hop, jazz and metal.
Linker’s fascination for Indian music began during his studies and he started learning intensively with two masters, Ustad Sabir Khan and Vidushi Tulika Ghosh. After travelling to India multiple times, years of lessons and devotion towards Indian music, Linker is now considered part of the musical families of his gurus. Ever since, Indian music has been a big part of Linker’s musical language: in his composed music he inspires western musicians with raga, and he is the first ever trombonist to perform Indian classical recitals.
With Linker’s broad musical background comes a diverse body of work, stretching from raga to counterpoint and from groove to rich orchestration. His pieces have been performed by orchestras and ensembles like the Noord Nederlands Orkest, the Nederlands Blazers Ensemble and the Ricciotti Ensemble. His work has been performed in all major Dutch concert halls and multiple works have been recorded. Besides his work as a composer, Linker is a sought-after arranger. His arrangements are performed in most of the concerts of the Nederlands Blazers Ensemble, the Dianto Reed Quintet and his own Nymphéas Trombone Quartet.
As a trombonist Linker plays different genres of music: as a chamber musician he performes contemporary, classical and early music with Insomnio, the Nederlands Blazers Ensemble and the Nymphéas Trombone Quartet. With groups like Nachtlicht Ensemble and Collective Move he is active in improvised music, often incorporating live electronics. However, as a performing musician, his biggest focus remains his solo recitals playing Indian Classical music with tabla players like Niti Ranjan Biswas and Imran Khan.
For his work as a composer, trombonist and improvisor Linker has been awarded the Grachtenfestivalprijs 2025, the Prijs voor Jong Talent 2023 from Kunst aan de Dijk Kortenhoef, a second prize at the Prinses Christina Compositieconcours, the Koninklijk Conservatoriumprijs voor jonge componisten, he won the composition contest of the Nederlands Blazers Ensemble and was awarded the prizes for culture of the municipality of Emmen and the province of Drenthe. In 2021-2022 he was a new maker in residence for the Grachtenfestival Amsterdam.
Linker studied classical composition and classical trombone at the Conservatory of Amsterdam with teachers Richard Ayres, Wim Henderickx, Willem Jeths, Meriç Artaç, Pierre Volders, Remko de Jager, Jörgen van Rijen and Bart van Lier.
