The Otamatone is a Japanese musical instrument developed
by the Cube Works Company along with Maywa Denki
and Novmichi Tosa. It is a musical-note shaped singing
toy which requires two hands to be played: while
one hand holds and/or squeezes the "head",
the other hand controls the pitch of the song by
sliding the finger up and down the stem. The sound
made by this instrument is often compared to the
sound of a theremin and a synthesizer. The otamatone
has three pitch levels and two volume levels...
