Theremin Controllers and Video Theremins: New interactive video game technologies like the Wii and Xbox Kinect can be hacked so that a player can use a game controller or, in the case of the Kinect, his own body to manipulate other synth devices and produce theremin-like sounds. As with most musical instruments, the more you spend on a theremin, the (generally) higher quality the instrument will be. Or even moving parcels of air through a shaft, as is done with brass and woodwind instruments. The theremin has been invented by a Russian physicist, Lev Sergueïevitch Termen (Лев Сергеевич Термен, or Leon Theremin). how does it work? The theremin typically consists of a box with two metal antennas which create an electromagnetic field. Way back in the early 1920s, when Léon Theremin worked at the Physico-Technical Institute in St. Petersburg, Russia, he noticed that when he moved his body in or out of an electromagnetic field produced by a radio frequency oscillating circuit, he changed its frequency [source: Harrison]. The Electro-Theremin is an electronic musical instrument developed by trombonist Paul Tanner and amateur inventor Bob Whitsell in the late 1950s to produce a sound to mimic that of the theremin. Invented in Russia in 1919 by Lev Sergeyevitch Termen, it is one of the world's earliest electronic musical instruments and is the grandfather of today's modern synthesizers. Although skilled players might make it look easy, playing the theremin requires great musical coordination and serious technical ability. How does a Theremin “antenna” work? It was developed by the best tournament the tools of the older time Clara talk more. Vibrating or striking a string, for example, as is done with a violin, cello, guitar, piano or hammer dulcimer. i watched someone play it, and i was like what the heck!?

How does a theremin work? - the theremin IS a synthesizer, albeit a very simple one. A theremin creates sound by broadcasting a signal to itself when a player's hand interrupts the magnetic field between its antennae. Theremin What is it? When the thereminist uses their body to interfere with the electromagnetic field, the instrument measures the difference between the fixed and the variable oscillators, and translates this difference to a pitch (or amplitude). This instrument is also known as Thereminvox and Aetherphone. The theremin is an electronic musical instrument that can be operated without directly touching it. The theremin works on the principles of heterodyning and capacitance. "Other Instruments." Theremin, also called Thereminvox, or Etherophone, electronic musical instrument invented in 1920 in the Soviet Union by Leon Theremin (also called Lev Termen). How it Works: The Science Behind the Magic. Though many people see it as a novelty primarily used to create horror-movie soundtracks, you can play many styles of music on the theremin. When you wave your hands near the antenna, you form a capacitor between your hand and the antenna. The theremin is a single oscillator electronic musical instrument with two metal rods used to control pitch and amplitude by the human performer using hand gestures. An Arduino theremin isn’t the same as the original theremin invented by Léon Theremin where you can control both amplitude and frequency.. As Theremin experimented, he discovered that he could change the pitch of an audio signal generated by this oscillator by changing the position of his body in relation to the electromagnetic field he was attempting to measure.

"The Lost Weekend" (1945): The theremin provides an eerie undertone as protagonist Don Birnam’s alcoholic cravings threaten to get the best of him. ... That is a capacitance and from the perspective of the theremin your body is an ac ground, so there is a virtual capacitance to ground which is a function of antenna material/length/voltage and your distance from it. The photoresistor is connected with the resistor to form a voltage divider.The Arduino reads the voltage out from the voltage divider.. Two antennas protrude from the theremin - one controlling pitch, and the other controlling volume. At the best you can learn a scale in 2 hours with professional guidance.
