The Diatonic Tembos are a striking outdoor musical instrument rooted in the principle of plosive aerophones. Players simply beat or slap the open end of each stainless steel tube using the included closed cell foam paddles, generating a pressure wave that travels the full length of the tube. Because each tube is a different length, each tube produces a unique wavelength and therefore a unique note, spanning the full C-major diatonic scale. The result is a collection of quirky, deep, and surprisingly resonant sounds that captivate players of all ages. Whether a curious toddler or a seasoned adult, anyone can pick up a paddle and instantly create music. Built from robust stainless steel, the Tembos are vandal resistant and engineered for the demands of public outdoor spaces, making them an ideal feature for parks, playgrounds, and community areas.
