In 2027, Interfinity turns its attention to language and communication. How does language shape the way we think, understand, and relate to one another? How does it emerge and change, and where do its limits lie? Bringing together music, science, literature, and art, the festival explores these questions from a different perspective each day. An international programme of world premieres, large-scale productions, and interdisciplinary projects ranges from contemporary music and art to centuries-old musical traditions and languages. Alongside the music, leading voices from science, literature, and the arts come to Basel for talks, conversations, and discussions. The festival opens on the final weekend of February with one of its major highlights: the long-awaited Swiss premiere of Georg Friedrich Haas’ 11.000 Saiten. Written for 50 pianos and ensemble, the work places the audience at the centre of a vast soundscape and has already played to sold-out houses in New York, Berlin, Vienna, Amsterdam, and Paris. At Interfinity, music and science are not simply presented side by side. The festival brings them into direct conversation, exploring the same questions through different disciplines and forms of expression. Music can make scientific ideas perceptible in new ways, while science can offer new perspectives on how we listen to and understand music.
