Originally based off the concept of a sheng (the ancient Chinese bamboo mouth-blown pipe instrument), but worn like an accordion, the Hohner Claviola is a very unique wind instrument. It has a set of piano keys on the right side that range 2.5 octaves and the left side has a set of pipes that range in length depending on the corresponding pitch.
This Claviola is in mint condition and functions perfectly. It includes the original carrying case and mouthpiece, which are also in mint condition, as well as the straps.
These instruments were only produced for a few months in the mid-1990s.
