is an site-specific sound sculpture by German artist Lukas Kühne and is located on a mountainside above the town of Seyðisfjörður, East Iceland.
The work is built of concrete and consists of five interconnected domes of different sizes. The heights of the domes are between 2 and 4 meters and they cover an area of about 30 square meters. Each dome has its own resonance that corresponds to a tone in the Icelandic musical tradition of five-tone harmony, and works as a natural amplifier to that tone.
Tvísöngur was opened to the public on September 5, 2012, and everyone can access it. It is embedded in the mountainside above the town, in a quiet area with a breathtaking view of the fjord. It offers an acoustic sensation that can be explored and experimented with by the visitor. The site’s solitude and tranquility offers a perfect setting for singing or music playing, alone, in harmony, for ones own pleasure or for an audience.
Lukas Kühne’s artworks are dedicated to space and frequency. He lives in Berlin and Montevideo, Uruguay, where he heads the workshop “Form and Sound” at the Faculty of Arts of the State University. The sculpture “Tvísöngur” relates to a series of works by the artist dealing with musical forms, one of which is the sculpture “Cromatico” built in Tallinn, Estonia in 2011.
To enjoy and experience Tvísöngur guest need to walk a gravel road that starts across from Brimberg Fish Factory, for 15-20 minutes.
