Welcome to a tour of the ten weirdest musical inventions ever crafted, where the line between sound and spectacle blurs into pure curiosity.
What Makes an Instrument the Weirdest Musical?
From ancient reed pipes to modern plasma speakers, each creation pushes the boundaries of what we consider a musical instrument. Some rely on physics, others on pure absurdity, but all share a common thread: they sound unlike anything you’d expect from a conventional orchestra.
10 Glass Armonica
Benjamin Franklin’s inventive mind wasn’t satisfied with staying in one creative lane. His most eccentric—and arguably favorite—creation was the glass armonica. The principle is simple: a fingertip gliding around a wineglass’s rim makes the glass resonate, producing a note. Inspired by a performer who played a melody on a series of glasses, Franklin engineered a single instrument that could cover a full range of pitches.
He mounted glass bowls of differing diameters on a rotating axle. The player dampens their fingers, positions them on the appropriate bowl, and lets the glass sing. The instrument became a sensation; composers like Mozart, Beethoven, and Strauss wrote pieces specifically for it.
Eventually, the armonica fell out of favor as pianos, with their greater volume, dominated concert halls. Its delicate tone could not compete with the booming presence of the piano, leading to its gradual disappearance from mainstream performance.
9 Le Petomane
If the human voice is the ultimate versatile instrument, then Joseph Pujol—known onstage as Le Petomane—took that notion to a literal extreme. In late‑19th‑ and early‑20th‑century France, he filled music halls with the sounds of controlled flatulence, delivering tuneful bursts on command.
The nickname “Le Petomane” translates to “the Fartomaniac.” Pujol discovered his talent while serving in the army, where his fellow soldiers delighted in his unusual skill. After a stint at his bakery, he moved to the stage and quickly became a star at the Moulin Rouche.
His technique involved “inhaling” air through the anus and expelling it with precise timing, allowing him to produce melodic phrases. Royalty even booked private performances. When an impostor tried to mimic his act with hidden bellows, Pujol sued and won, cementing his status as the one true Petomane. He later retired to his bakery and started a biscuit factory.
8 The Great Stalacpipe Organ
Hidden beneath Virginia’s Luray Caverns lies the world’s largest musical instrument: the Great Stalacpipe Organ. Spanning 3.5 acres of underground chambers, it uses natural stalactites struck by mechanical hammers to create tones.
Designed in the 1950s, the organ was a solo effort by Leland W. Sprinkle. While the crystal‑clear stalactites naturally ring when hit, Sprinkle spent three years filing them to precise pitches, turning the cavern into a massive, resonant keyboard.
Visitors can hear live performances, and recordings have been released on CD. In 2011, a composer wrote the piece “In the Cave” expressly for this subterranean marvel.
7 Fences
Robert Frost famously wrote, “Good fences make good neighbors.” Musicians Jon Rose and Hollis Taylor decided that fences could also make good instruments. Their project, Great Fences of Australia, saw them traverse thousands of kilometres, bowing the taut wires of farm fences to generate screeching tones, while drumsticks provided percussive beats.
The concept spread worldwide, inspiring concerts on specially designed fences across continents. Rose and Taylor also documented the lives of fence builders and explored the cultural forces that gave rise to these sprawling structures.
6 Zeusaphone Or Thoramin
Who doesn’t love a controlled bolt of lightning? The Zeusaphone (also called the Thoramin) merges electricity with music, taking its name from the thunder‑god Zeus and the Norse god Thor. By connecting a Tesla coil to an electronic instrument, the coil becomes a plasma speaker.
When the coil’s stored charge discharges into the air, a spectacular arc of plasma forms, producing a thunder‑like sound. The visual spectacle pairs perfectly with the audible effect, turning raw electricity into a musical performance.
5 Wintergatan Marble Machine
The Swedish folktronica group Wintergatan spent 14 months engineering a one‑of‑a‑kind instrument: the Marble Machine. This intricate contraption of gears, wheels, and switches uses falling marbles to generate sound, while a snare drum component relies on basmati rice for its crisp snaps.
Documented through a series of YouTube videos, the machine went viral, amassing over 28 million views. Unlike many novelty instruments that repeat a single tune, the Marble Machine is fully playable, and it even toured with the band in 2016.
4 Vegetable Orchestra
While the Stalacpipe Organ may endure for centuries, the Vienna Vegetable Orchestra proves that musical creativity can be delightfully fleeting. Founded in 1998, the ensemble crafts instruments from everyday produce—drilled carrots, pumpkin drums, and pepper horns—to generate unique timbres.
The orchestra’s ever‑changing palette of vegetables grants them complete control over sound, as each harvest yields new possibilities. After performances, the leftover vegetables are turned into a hearty soup served to the audience.
3 Pyrophone
Traditional pipe organs use pressurized air to vibrate pipes, but in 1873, Frederic Kastner patented a fiery twist: the pyrophone, also known as the fire or explosion organ.
The instrument harnesses a quirk of physics—when a flame burns within a tube under the right conditions, it produces a note. By adjusting the flame’s size, the performer can turn notes on and off.
Despite its dramatic concept, the pyrophone never gained popularity. Even Henry Dunant, founder of the Red Cross, was hired to travel Europe promoting the instrument, yet audiences remained indifferent.
2 Beer Bottle Organ
Everyone has blown across a bottle’s opening to produce a pitch, but the beer bottle organ turns that simple trick into a full‑scale keyboard. By filling bottles to varying levels, each produces a distinct note when air is blown over its mouth.
To maintain consistent tuning, the beer is replaced with glycerol, preventing evaporation from altering the sound. A key press opens a valve that directs air over the bottles, playing the desired note.
The concept dates back to 1798 on the German island of Helgoland, where a church congregation, weary of constantly tuning their organ, commissioned a glass‑bottle organ that would remain stable regardless of temperature or weather.
1 Floor Buffer, Vacuum Cleaners, Rifles
Sir Malcolm Arnold may be better known for his serious compositions, but his most famous work by far is a tongue‑in‑cheek “Grand, Grand Overture.” Commissioned in 1956, the piece calls for an organ, full orchestra, three vacuum cleaners, a floor polisher, and four rifles—perhaps a playful jab at Tchaikovsky’s cannon.
During the 2009 Last Night of the Proms, pianist Stephen Hough, conductor Jiří Bělohlávek, and violinist Jennifer Pike operated the vacuum cleaners, while naturalist Sir David Attenborough famously played the floor polisher supplied by Arnold’s family. True to tradition, the performers of the vacuum cleaners and floor polisher were “shot” at the performance’s conclusion.
