Tunelle is a Spring instrument. Its name is a contraction of two words that characterise this instrument sonically and visually: 'tuned tunnel'.
We've built two different versions of this instrument - Metal Tunelle and Wooden Tunelle.
Springs always ring in several pitches at the same time. Depending on the articulation used, different pitches of the same spring can be heard more or less clearly.
The Spring instrument group
As funny as it may sound, the idea for Spring instruments occurred on a sleepless night when restlessly laying on an old and occasionally ringing spring mattress.
Springs are actually used in so many objects that people use daily (pens, table lamps, watches, cars, you name it!), that we started collecting springs and playing around with their sonic qualities. A whole new world of long metallic resonances emerged!
