Tactile interface where ropes are connected to sensors on spring-loaded coils (balancers) and custom built software that transforms rope movements to sound and music

The Vocal Chorder exists in different versions: As an instrument for performers, and as an audience-interactive installation. Performances with the Vocal Chorder have taken place at: Berwaldhallen, Piteå Acusticum, Kungliga Operan, Operadagen Rotterdam, Cape Town Opera, Spotify Winter Event, Toronto Congress Centre, Liszt Academy Budapest, Croatian National Opera Rijeka, GöteborgsOperan, Den Anden Opera Copenhagen.

Opera singers can use the Vocal Chorder, a large interactive instrument, to add new elements to their performance. The device allows performers to interactively accompany themselves through pushing, leaning on, and bending steel wires. Audience members can also use the instrument to interact with the operatic voice. When a person steps into the Vocal Chorder, its wires enable
full-body interaction to explore the sounds and the interactive pyramid projected in front of the performer. It is a visualization of the child in Ray Bradbury ́s short story “Tomorrow ́s Child,” born in another dimension and perceivable by its parents only as a pyramid.

Furthermore, The Vocal Chorder has been developed into a gigantic version, allowing multiple performers (such as a choir in “Calligrammes”) to perform together in the instrument.
