Theremin is a musical instrument that was created in 1928 by a Russian inventor Leon Theremin. It is played without touching any of the components and the device was able to determine the pitch and volume of the sound by calculating the distance between your hand and the two antennas. The vertical antenna changes the pitch while the horizontal antenna changes the volume of the sound. It was an unusual and strange instrument that was unknown to the majority of the public.
Component – Infrared Obstacle Avoidance Sensor, Sound module
Theremin had a simple idea of creating sound by judging the distance of your hand, stripping away all the complex gesture in order for a person to play a musical instrument, removing all the agility that was required from the player. It provides an easy control that allows even people with disability to play music.
