The Otamatone is a simple instrument that generates digital synthesizer-like tones when you tap or slide your finger down the neck. Otamatones cost roughly $26 on Amazon and come in common hues like as white, blue, or black. This device was invented by Hirotoshi Otomo and released in 1998. It became a hit with musicians because of its low price and small size. However, it does not work without electricity which limits its use outside of the studio. Otomo later introduced the Otonal, which is similar to the Otamatone but uses actual notes instead of synthesizer sounds. This makes it easier to play traditional Japanese instruments such as the shakuhachi and koto because they only have a few different pitches instead of hundreds. The Otonal can be connected to a computer via USB and controls are shown on screen so no special software is needed. In addition, it can be used in place of a microphone for recording vocals. Future products from Otomo included the Mocap, which records motion data from your body in order to create new music, and the Kizuna, which connects several Otamatones together to make an octet. Otomo died at age 53 in 2003 due to complications from diabetes. But he still manages to inspire many musicians today through his innovative ideas.
