The Strange Electric Voice Behind Classic Rock

Before synthesisers became familiar fixtures on rock stages, the theremin offered musicians something genuinely uncanny. Its pitch and volume are controlled by moving the hands through electromagnetic fields, leaving the performer apparently conducting an invisible instrument.

That sound sits somewhere between a human wail, a bowed string and a radio drifting out of tune. It could be eerie, romantic or hilariously over-the-top, which made it perfect for a genre increasingly interested in science fiction, psychedelia and studio experimentation.

For Australian listeners, the instrument’s most recognisable moment may arrive through “Good Vibrations”, a song still heard across ABC music programming, commercial radio and classic-rock playlists. The famous vocal melody is inseparable from that swooping electronic colour, even though the instrument used was a specialised variation.

The theremin never became as common as the Hammond organ or the electric piano. Instead, it remained a secret weapon: an occasional burst of strange atmosphere that could make a familiar guitar band sound as if it had picked up a transmission from somewhere beyond the stage lights.

From laboratory curiosity to pop sensation

Russian inventor Lev Termen developed the theremin in the 1920s. Unlike a keyboard or guitar, it has no frets, keys or strings. One hand controls pitch near a vertical antenna, while the other alters volume near a horizontal loop. Small movements can produce dramatic changes, and precise intonation takes extraordinary discipline.

Its early public image was shaped by concert music, horror cinema and science fiction. The instrument’s ghostly glissando became a shorthand for alien worlds and psychological unease, preparing audiences to recognise its voice before rock musicians adopted it.

The Beach Boys made it unforgettable

On the Beach Boys’ “Good Vibrations”, session musician Paul Tanner played an electro-theremin, often called a Tannerin. It was related to the original instrument but used a sliding control rather than the classic two-antenna setup. That distinction matters: the record’s sound is theremin-like, though it was not a standard theremin performance.

The effect transformed a carefully arranged pop song into something expansive and dreamlike. In Australia, where the track remains a reliable singalong on oldies stations and at pub jukeboxes, that wavering tone can still stop listeners in their tracks. It is a brilliant example of a studio texture becoming the emotional signature of an entire song.

Jimmy Page turned the noise into theatre

Led Zeppelin brought the instrument into heavier territory. Jimmy Page used a theremin during “Whole Lotta Love”, especially in the extended middle passage, where the sound bends, shrieks and circles around the stereo field. It feels less like a melody than an electrical disturbance breaking through the riff.

Page also used the instrument onstage, making it part of rock performance rather than a hidden studio colour. The gesture suited the era’s appetite for spectacle: towering amplifiers, dramatic lighting and musicians willing to make noise with anything within reach.

The instrument is often misidentified

The theremin’s cultural shadow is larger than its confirmed appearances. The opening figure of The Who’s “Baba O’Riley” is frequently mistaken for one, but it comes from a Lowrey organ processed through the band’s studio setup. Its pulsing pattern has a futuristic character, yet the playing method is entirely different.

That confusion reveals how strongly the sound has become a genre signal. A swooping synthesiser, a guitar run through unusual effects or a distant vocal can all be described as “theremin-like”. Producers understood that the suggestion of the instrument was often enough to summon mystery without demanding a specialist performer.

Why rock kept returning to the strange sound

Classic rock valued instruments that disrupted the expected relationship between player and audience. A guitar could roar, a mellotron could imitate an orchestra and a theremin could appear to sing without being touched. Its physical invisibility gave it a natural place in psychedelic and space-rock arrangements.

The same instinct continues in contemporary music. A band blending styles can use an old electronic voice to make familiar rhythms feel unstable or cinematic. That adventurous spirit connects classic experimentation with Austin’s rhythmic hybrids, where rock’s vocabulary keeps expanding through unexpected combinations.

A rare instrument with a lasting afterlife

Few bands build entire careers around the theremin because it is difficult to play, hard to keep in tune and not always easy to place in a live mix. In a venue such as Melbourne’s Forum Theatre or Sydney’s Enmore Theatre, its quiet electromagnetic gestures can disappear beneath drums and amplified guitars unless the arrangement leaves room.

That scarcity is part of its appeal. From a Brisbane rehearsal room to a late-night set on community radio such as PBS 106.7FM, a convincing theremin passage still sounds like an event. It carries the memory of old science-fiction films while remaining open to new uses in garage rock, experimental pop and heavy music.
