She moves through space / Clara de Asís

Written for viola, organ/piano, and electronics, the piece will explore interdependent relationships between dynamics of attention, spatial trajectories, time, and the perceptual fluctuations that emerge from these interactions.
Drawing from my ongoing interests in attention, perception, and hybrid tuning systems, this work approaches these acoustic instruments through a lens often associated with electronic music; one grounded in frequency interaction, filtering, spatial diffusion, perceptual thresholds, and oscillating gradations of tone.
New composition commissioned by Echonance and Orgelpark.

Soliton(e) Star/
Catherine Christer Hennix

The drone piece Soliton(e) Star unfolds as a precisely tuned, continuous harmonic field where interacting frequencies create subtle beating patterns and a deeply immersive listening space, inspired by the stability of “soliton” waveforms.

Hidden Melodies/
Tom Johnson

In Hidden Melodies, Tom Johnson (1934—2024) explores the beauty of simple numerical processes. Patterns unfold gradually, revealing subtle symmetries and discreet surprises within strictly defined structures. The piece exemplifies Johnson’s minimalist clarity: music that discovers itself through logic, repetition, and attentive listening.

बगलामुखी (Bagalāmukhi)
/ Nirantar Yakthumba

This piece grows from Nirantar’s study of North Indian ragas, Arabic maqāmāt, and quarter-comma meantone. Bagalāmukhi proposes 42 new tonalities in an extended meantone system, each with melodic fragments that reveal its character and guide improvisation. The work invites performers to learn these tunings deeply and relate them to their own musical practice.

Instrument and Voice / Peter Ablinger

Ablinger transforms spoken voice into precise musical patterns, which the instrument seeks to mirror. The piece exposes the tiny details of speech—its pitches, noises, and rhythms—turning language itself into music.

13 visions
For Solo Violin/
Clara Lévy

13 Visions is a cycle of short pieces for solo violin, each shaped as a distinct sonic image. Inspired by an imagined conversation between Hildegard von Bingen and Pauline Oliveros, Lévy weaves medieval clarity with deep listening practices, creating a meditative sequence where fragile colors and quiet gestures unfold with intimate focus.

Three voices /
Morton Feldman

Three Voices (1982) layers two pre-recorded vocal lines with one live singer, creating a delicate web of repeating patterns and softly shifting harmonies. Feldman’s characteristic quietness and long durations invite close listening, as the three intertwined lines drift in and out of focus like slowly changing light.

Heliacal Waves /
Duo Pip – Torstein Lavik Larsen & Fredrik Rasten

The duo trumpeter Torstein Lavik and Larsen and guitarist Fredrik Rasten create immersive soundscapes where time seems to stretch, shimmer, and slow down.
Their music invites introspective listening, perfectly in tune with our ongoing festival exploration of music as a spatial and perceptual experience. Heliacal Waves is composed with support from Musikkfondene and Kulturdirektoratet.

Miniature in Five Parts for organ /Composer, alone (1) for piano /
Jürg Frey

Jürg Frey’s music is grounded in attention, stillness, and the experience of time as an open, shared space. His works unfold slowly, giving equal importance to sound, silence, and resonance. Rather than directing the listener, Frey creates conditions for listening in which subtle changes, fragility, and presence come to the foreground, and the surrounding space becomes an integral part of the music.

Stromsänger for six voices and electronics
 / Christina Kubisch

“The general theme of the composition is the idea of sounds that travel. During a tram ride from the city up to the hills on an old tram, I discovered not only stunning views of the surrounding landscape, but also a special soundscape. Wearing custom-made induction headphones, I could hear the normally hidden electromagnetic fields of the tram. These sounds were so impressive and musical to me that I immediately decided to base my piece for Trondheim Voices on this discovery.”

Christina Kubisch

Stromsänger is a collaboration between sound artist Christina Kubisch and the Norwegian vocal ensemble Trondheim Voices.

Composers

Peter Ablinger (Austria)
Ablinger first studied graphic arts and became enthused by free jazz. He completed his studies in composition with Gösta Neuwirth and Roman Haubenstock-Ramati in Graz and Vienna. Since 1982 he has lived in Berlin, where he has initiated and conducted numerous festivals and concerts. In 1988 he founded the Ensemble Zwischentöne. In 1993 he was a visiting professor at the University of Music, Graz. He has been guest conductor of ‘Klangforum Wien’, ‘United Berlin’ and the ‘Insel Musik Ensemble’. Since 1990 Peter Ablinger has worked as a freelance musician. From 2012-2017 he was Research Professor at the University of Huddersfield. In 2019 he was Guest Professor at the Royal Conservatory in The Hague and Leiden University. Since 2000 he has been engaged in various forms of non-institutional teaching and work with private students. 



Clara de Asís (SP)
Spanish artist and experimental composer whose work engages with the interplay of acoustics, temporality, and the praxis of attention. De Asís explores how sound perception is shaped by specific social and material contexts, using electronics, sound synthesis, idiosyncratic combinations of found objects, and traditional instruments. Her practice spans performances, audio works, and installations, often focusing on resonance, spatial interaction, and subtle acoustic shifts over time. For Echonance, Clara will compose a new piece for organ(s), viola, traverso, and electronics. Developed at Orgelpark, the work will take the form of a modular, open score—designed for interpretive flexibility and for adaptation across performance settings and keyboard instruments.

Patricia Bosshard
Patricia Bosshard has followed a unique, experimental path, taking her violin to all kinds of performances and collaborations that have taken her to the US, France, and Europe for various festivals and contemporary events.
After classical training in Montreal, composition and electroacoustics in Geneva, and jazz in Lausanne, she developed her own language based on experimental and improvised music, emphasizing the quality of listening and the contemplation of sound.
Her compositions reflect her work with electronics and her questioning of the world of sound that surrounds us. Recent compositions for various european contemporary music Ensembles such as ONCEIM (Paris 2019), CH.AU (Vevey 2020, 2025), the LGBS quartet (France-Switzerland 2021), and the Contrechamps and baBel ensembles (Geneva 2024).
She writes regularly for Theater and explores the perhaps non-existent link between video and electronic music (with Nicolas Wintsch, Cie Dynamo). She is the author of the jingles for the Lausanne M2 metro stations.
Very active on the European improvised music scene, she performs with Xavier Charles, Les Champignons du Futur, ONCEIM, the big Orchestra Eustache.

Morton Feldman

Jürg Frey

Catherine Christer Hennix
(1948–2024) was a Swedish composer, mathematician, and artist whose work merges minimalism, just intonation, and mystical thought. A close associate of La Monte Young and Marian Zazeela, she developed a rigorous, long-duration approach to sound and harmonic perception.

Christina Kubish (DE)
A pioneer of sound art, Christina has spent decades developing a singular practice rooted in sound, space, and perception. While her work spans concerts, performances, video, and visual art, she is best known for her sound installations and electroacoustic compositions, where she poetically reveals hidden layers of our sonic environment. Christina has forged a unique artistic practice by adapting technologies such as ultraviolet light, solar energy, and electromagnetic induction, merging audio and visual elements into multisensory experiences that invite participants to become active listeners. Since 2003, her ongoing series Electrical Walks has taken place worldwide, transforming urban spaces into audible landscapes of electromagnetic fields.

Christina will create a new work for one of Echonance’s most treasured adventurous companions, the ONCEIM Orchestra, together with electronics. This collaboration promises to be a highlight of Echonance 2026 and a milestone for the festival, furthering our commitment to bold and radical artistic propositions.

Christina Kubisch has a unique way of working with musicians, and it all begins with listening. In each city she visits, she uses her special coil headphones to collect electromagnetic sounds—buzzes, hums, and signals that normally go unheard. She often describes this process as a kind of mapping: each city has its own invisible soundscape, shaped by its specific infrastructures and electrical systems.

She then creates a file with these recordings and shares it with the musicians, inviting them to respond freely to what they hear. These first reactions form the foundation of the musical material that follows. From there, she begins to “orchestrate” this sound material, shaping durations, textures, and densities. The result is music with very open harmonies and flexible forms. The harmonic language shifts between microtonal and tonal elements, and the structure unfolds in a series of interconnected movements, like a chain of evolving moments. Notation is developed gradually, reflecting both what happens in rehearsals and the creative input of the musicians.

Duo Pip
Led by the trumpeter Torstein Lavik Larsen (NO) and guitarist Fredrik Rasten (NO/DE), Pip creates enduring sonic landscapes through a patient, precise, and attentive approach to sound. Justly intonated harmonies, airy textures, and slow melodies form an organic music in which listeners can both surrender and actively explore its multilayered sonic facets. Since forming in 2006, the duo has developed a distinctive voice spanning improvisation and collective composition.Continuing their experiments with just intonation, microtonality, extended techniques, and invitations to introspective listening, Fredrik and Torstein will compose a new work for organs, guitar, trumpet, and electronics (and perhaps more!), specially developed at Orgelpark.

Ensembles & musicians

Orchestre de Nouvelles Créations, Expérimentations et Improvisations Musicales ONCEIM (FR)
Onceim is an orchestra made up of thirty-five high-level musicians with a variety of musical backgrounds: improvised music, jazz, free jazz, classical and contemporary and experimental music . When he created Onceim in 2011, Frédéric Blondy sought to take the exploration of sound creation to a dimension of contemporary research. With Onceim, it’s always about creating, innovating, breaking free from the limits that instruments and classical musical writing sometimes impose. Thus, in the individual and singular precision of each musician, all are at the service of the whole to produce a result never known in advance and necessarily collective.

Robin Hayward

Reinier van Houdt
Reinier van Houdt started working with tape-recorders, radio’s, objects and various string-instruments at a young age. He studied piano at the Liszt-Akademie in Budapest & the Royal Conservatory in The Hague. He developed a fascination for matters that escape notation: sound, timing, space, physicality, memory, noise, environment – points beyond composition, interpretation and improvisation.
