Created in 1920 by Russian physicist Lev Sergeyevich Termen, known as Léon Theremin, he is the pioneer of electronic instruments, marking the history of music with his innovation.
Unlike any guitar or piano, the theremin does not require physical contact: the musician manipulates electromagnetic fields with precise hand movements, as if dancing with the air.
This characteristic, combined with its sound that evokes the supernatural, makes it a unique, almost alien, piece in modern music.
Why does it continue to intrigue artists and listeners in 2025? Let's dive into the history, science, and cultural impact of this convention-defying instrument.

In this article, we will explore the origins of theremin, its intriguing mechanics, its presence in pop culture and its rebirth in contemporary music.
Have you ever wondered how a device can transform gestures into ghostly melodies?
Get ready to find out why the theremin It is more than an instrument, it is a sensory experience that transcends the ordinary.
The Origin of a Cosmic Sound
Imagine a laboratory in post-revolutionary Russia, where a young scientist, passionate about music and electricity, discovers something unexpected.
Léon Theremin, while researching proximity sensors in 1920, noticed that the interference of his hand in an electromagnetic field produced sounds.
This accident gave rise to the theremin, initially called “aetherphone”.
He presented the instrument to Vladimir Lenin, who, impressed, ordered 600 units to spread the Soviet innovation.
The trajectory of the theremin was not only scientific, but also political. Theremin took his invention to Europe and the USA, where it was patented in 1928.

Despite initial enthusiasm, the Great Depression limited its commercial success.
Still, its unique sound soon found its way into concerts and, later, into soundtracks.
Interestingly, Léon Theremin's life reflects the turmoil of his era.
In 1938, he was kidnapped by Soviet agents in New York, forced to return to the USSR and work on espionage projects.
His personal story, full of intrigue, reinforces the mystical aura of the theremin, an instrument that seems to carry secrets from another world.
How Does Theremin Work?
Unlike any traditional instrument, the theremin operates with two radio frequency oscillators that generate electromagnetic fields.
A fixed oscillator and a variable oscillator create a frequency difference, which translates into audible sound. Two antennas control the sound: the vertical antenna adjusts the pitch of the note, while the horizontal antenna adjusts the volume.
Touch the theremin requires almost surgical precision. The musician moves his hands in the air, without tactile reference, altering the electrical capacitance.
Moving your hand closer to the pitch antenna raises the note; moving it away from the volume antenna increases the intensity. This invisible interaction creates a continuous sound, with glissandos reminiscent of a supernatural violin.
The complexity of theremin is in the absence of keys or strings. According to thereminist Carolina Eyck, "it's like painting in the air, requiring total control of the body."

Mastering it can take years, but the result is a unique musical expression that seems to float between the human and the extraterrestrial.
The Theremin in Pop Culture
THE theremin captured the popular imagination by becoming the voice of science fiction films of the 1950s, such as The Day the Earth Stood Still (1951).
Its sound, described as an alien lament, defined the genre. Miklós Rózsa, composer of Spellbound (1945), used the theremin to evoke psychological tension, a landmark in soundtracks.
In pop music, bands like The Beach Boys (on “Good Vibrations,” albeit with a Tannerin) and Led Zeppelin explored similar sounds.

In 2025, artists like Radiohead and Jean-Michel Jarre still embody the theremin in performances, maintaining its relevance. Festivals like "Hands Off" in England celebrate its global community.
Besides music, the theremin even inspires geek culture. Virtual reality games and apps in 2025 simulate this experience, bringing new audiences closer.
Its futuristic aesthetic makes it a timeless icon, as if it were a portal to another dimension.
The Theremin Revival in 2025
The interest in theremin never disappeared, but 2025 marks a vibrant rebirth.
Moog Music, a pioneer in synthesizers, has released the Claravox Centennial, a modern model that pays homage to Clara Rockmore, the greatest thereminist in history.
This instrument combines analog technology with MIDI connectivity, allowing integration with music software.
Thereminists such as Lydia Kavina and Grégoire Blanc offer workshops at events such as the Theremin Academy in Berlin.
A recent statistic from Moog Music reveals that sales of theremins grew 15% between 2023 and 2024, driven by independent musicians and electronic producers.
The instrument attracts those looking for unique sounds in genres such as ambient and experimental.
Accessibility has also increased. Kits like the Open Theremin, an open-source project, allow enthusiasts to build their own instruments.
Thus, the theremin is no longer a museum artifact, but a living tool for modern musical creativity.
Why Does the Theremin Sound Like It's from Another Planet?
The sound of theremin It is often compared to an extraterrestrial human voice, with tones that oscillate between the melancholic and the supernatural.
This quality stems from its ability to produce continuous glissandos, without the pauses typical of other instruments. It's as if the musician were conjuring melodies from a cosmic void.
Similarly, touching the theremin It's like conducting an invisible orchestra. Every gesture is a note, every movement an emotion, creating an almost magical connection between the artist and the sound.
This intangibility is fascinating, as it challenges our perception of how music should be made.
In contemporary culture, the theremin resonates with the pursuit of innovation. By 2025, it is used in game soundtracks such as Starfield and in live performances that mix electronic and classical.
Its alien aura continues to inspire, as if it were an echo from a distant future.
Practical Examples of Theremin Use
Want to try the theremin? Imagine creating a soundtrack for a short thriller film.
With a Moog Etherwave, you adjust the tone to create tension by slowly moving your hand near the height antenna. The result is a chilling sound, perfect for mystery scenes.
Another example: in a live performance, combine the theremin with an effects pedal to create psychedelic textures.
A thereminist might play Debussy's “Clair de Lune,” using subtle vibrato to evoke an alien moon, enchanting the audience.
These scenarios show the versatility of the theremin.
Whether in home studios or on stage, it offers endless possibilities, from classical melodies to electronic experimentation, always with an otherworldly touch.
