Product Description (excerpt from the website) The theremin was invented in the 1920s by the Russian scientist Theremin. It is said to be the ancestor of electronic musical instruments, including modern synthesizers. The way you play it, moving your hands in the air without touching the instrument, is like watching an elegant dance. Also, the analog electronic sound produced has a strange nostalgic feeling. Features Authentic, with the right hand controlling the pitch and the left hand controlling the volume. Small and lightweight, with a built-in speaker, so anyone can play it anytime, anywhere. It can also be connected to an amplifier or amplified speakers, allowing you to enjoy various musical expressions.
