Claviola

The Claviola is a musical instrument that was designed in the 1960s by Hohner technician and designer Ernst Zacharias (inventor of the Pianet and Clavinet). The instrument was produced for a few months in the late 1990s before being discontinued.

Similar to a melodica (which is still in production), but worn like an accordion and played like a bagpipe, the claviola has a set of piano keys on the right side that range 2½ octaves. The left side is a set of pipes that range in length depending on the corresponding pitch.
