The counter-rotating vibrations are harmonised in the sound chamber using an opus spicatum (Latin for ‘spiked brickwork’). This technique was already used in ancient civilisations to counteract undesirable effects. Within the European cultural sphere, there are many examples of Roman architecture where the construction method and the effect of the opus spicatum can still be experienced two thousand years later.
How Opus spicatum works
The opus spicatum at the Klanghaus was built into a trench. Various materials used in this structure serve to dampen and reverse the polarity of the rising energy and information from the water veins: Jurassic limestone gravel with sharply broken edges and monastery bricks, which were laid in a specific pattern taking polarity into account. The vibrations of the water veins are redirected and altered within the bricks.
Active perception of vibrations
Many water veins flow towards the Klanghaus from the south. Practical tip: Locate a water vein some distance from the Klanghaus, for example using a divining rod or a pendulum. Pay attention to your bodily sensations – maintaining a loving connection with yourself and the world around you is essential here. Now follow the course of the water vein towards the Klanghaus. At the point where the influence of the water vein disappears, you are in the area of the Opus spicatum. Note: Dowsing and meditative exploration techniques can be learnt.
The energy assessments and the construction of the Opus spicatum were supported by Klangwelt Toggenburg and Asterito AG.

‘The opus spicatum was already used in ancient civilisations to counteract undesirable effects and can still be seen today in Roman architecture.’
Resonance stone
Inside the Klanghaus there is a single monastery brick which, as a ‘resonance stone’, is connected to the bricks laid in the ground. Just over a thousand monastery bricks have been laid in the ground around the Sound House in a precisely defined herringbone pattern (Opus spicatum). The resonance stone has the same dimensions and properties as the bricks in the ground, with one difference: it alternates polarities and is sometimes even without polarity.
