A concert from the Nordic forests. The hall sings, claps and dances a forest into being while Ouros Animation's film plays above the orchestra. The children learn the songs in advance from the songbook, so they arrive ready to take part.

The hall decides which way the music goes. Three times during the concert the audience chooses between two paths (A or B) – and every outcome is fully composed. Four string players from the orchestra step forward as the Prince, the Elf, the Dwarf and the Giant; Mathias narrates with keytar.

“It is a great pleasure to work with Mathias and the team behind The Neverending Maze. For several years we have heard about his interactive formats from the other symphony orchestras, and it is wonderful now to experience ourselves how the audience is engaged and how classical music is brought into play in new ways.”Adam Stadnicki, Head of Music and CEO, Sønderjyllands Symfoniorkester · press release, May 2026, translated from Danish
“Composers like Mathias take charge of developing the concert concepts themselves: projects that arrive thoroughly worked through and ready to implement. One of the hallmarks of his works is their continuous development, created in close dialogue with the audience.”Maja Joss-Børch, DR Musikariet / Sønderjyllands Symfoniorkester · written recommendation, 2024, translated from Danish
“Sheet music that is impeccably prepared and gives musicians and conductor the best conditions to make music that sounds good, means something and engages.”Jesper Mikkelsen, producer for children, young people and outreach, Aalborg Symphony Orchestra · written recommendation, translated from Danish
“The work is not just composed but conceived and thought through by Mathias Madsen Munch, who himself narrates, plays and sings the story for the audience. When the music is also finely orchestrated by Thomas Bryła, it is a pleasure for the musicians to take part. They can feel when they are part of something good and meaningful.”Henrik Vagn Christensen, conductor of The Neverending Maze with Aalborg Symphony Orchestra, 2024 · written recommendation, translated from Danish
“I have experienced both The Neverending Maze and Mossy Mogens as effective and strong concerts for children. The music is catchy and atmospheric, and working with Mathias has been thorough, accommodating and flexible.”Jonas Ervolder Bové, percussionist, Aalborg Symphony Orchestra · written statement, translated from Danish
“Mathias' ability to compose innovative and interactive works for children has a marked influence on how we reach our young listeners.”Martha Marie Petri, children, young people and outreach, Aarhus Symphony Orchestra · written recommendation, translated from Danish
“The Neverending Maze helps open the world of classical music to children on their own terms. The work shows how close collaboration between composer and symphony orchestra can create a magical universe that captures children's curiosity.”Cecilie Wallengren, senior adviser, the Augustinus Foundation · press release, May 2026, translated from Danish
“For the past ten years or so Mathias Madsen Munch has been an important part of the children's culture effort in Helsingør Kommune, one of the recurring artists that pupils in our schools meet as a teacher. My warmest recommendation for any project that revolves around music and innovation.”Ida Wettendorff, children's culture consultant, Helsingør Kommune · written recommendation, translated from Danish
Everyone below has worked with Mathias directly. We are happy to put you in touch – just ask.






Piano, Mezzo and Forte are orchestra sizes, not instruments: the woodwind and brass line-up defines each one, and the string section follows your orchestra. Pick the one closest to your permanent line-up to see which works are played in that size today and which are planned – developed with the next orchestra that programmes it. Larger formations on request.

Type the name of your orchestra to see which of the three sizes it typically matches. The match is based on permanent woodwind and brass positions as published by the orchestras (September 2026). Line-ups for children's concerts vary, so we always confirm with you.
Not listed? Write to us with your woodwind and brass line-up and we will tell you which size fits.
The children arrive knowing the songs and the rules of the game: Danish teaching material exists for The Neverending Maze (Levende Musik i Skolen) and Mossy Mogens (songbook, book, audiobook and teaching films with Forlaget Dansk Sang), and browser-based material is in development. Teacher courses, workshops and the material itself are on the learning page.

No accounts, no scores, no way to fail – the child finds a musician, plays her melody and sees it in the sky. Danish prototype.
Open Tocanta ↗︎In 2013 Mathias won the competition for new interactive works for children held by the Danish Composers' Society, DR and Levende Musik i Skolen. The winning work, The Neverending Maze, went on a school tour with Levende Musik i Skolen – and it is still touring. At DR he became house composer and developed The Dreaded Pirates and Ragnarok in the same universe; in parallel he toured Baron von Münchhausen in a small set-up.
Aarhus Symphony Orchestra asked for The Neverending Maze as a full orchestral work in 2023 – nominated for the Carl Prize, a YAMawards finalist – and it has since been played by Aalborg, Sønderjylland and, in English, City Chamber Orchestra of Hong Kong. Mossy Mogens premiered with Aalborg Symphony Orchestra in 2024, BIOFONIA at COP30 in Belém in 2025. Mathias is on stage – or right behind it – in every production.

The Augustinus Foundation supports the development with the Danish regional orchestras, 2025–27: the three sizes are tested there first. In parallel we develop the international versions – script-based narration that moves into a new language, and line-ups that fit orchestras outside Denmark. Hong Kong played The Neverending Maze in English in 2025; BIOFONIA premiered in Belém.

Composer · Artist · Educator. Concept, music and storyteller on stage. Master's degrees in film composition and educational psychology. House composer at DR Musikariet 2017–2019. Carl Prize nominee and YAMawards finalist 2024.
