The Resonance Echo Tubes' design intrigues children and encourages them to spontaneously experiment with sound.

With two people whispering, singing or transmitting other sounds from one end of the tube to the other, no sounds can be heard outside the instrument. Only the person at the other end can be their recipient. This unconventional procedure makes it possible to creatively integrate those visiting a musical playground. With a little imagination, children can immerse themselves in the world of spontaneous and unique sounds.

The Resonance Echo Tubes is only available with ground anchors. It comes with a sturdy corrugated tube up to 15 meters long. The corrugated tube makes it possible to set the components at any distance up to 15 meters. This is the most professional and stable attachment of the instrument to soft surfaces (e.g. lawns, sand). The 2 tubes when installed are in 2 heights: 110cmH and 140cmH. The speaking discs are 35cm diameter.
