The Tiane horn chromatic was launched in 2017. The idea was to embed a regular three octave harmonica into a larger metal pipe in order to leverage the inner resonance of the pipe and therefore resulting in a more rounded and internally echoed sound.
The principle is similar to the Koch horn chromatic. Even though in that case the pipe has openings on both sides. A patented was acquired in 2017 with patent number: ZL 2017 2 0578099.2 (published under CN206726749U)
