- Unless you really like music, then maybe you do know.
Have you ever heard of these crazy instruments? Or maybe you have played some of them and have something to add to the list!
Hydraulophone
Imagine an instrument played by sticking your fingers into streams of water. A hydraulophone uses flowing water to control sound, making it look more like a bizarre scientific experiment than a musical instrument.
Shofar 
Made traditionally from a ram’s horn, the shofar produces powerful, raw blasts rather than conventional melodies. It has deep religious and cultural significance in Jewish traditions.
Glass Armonica
Invented by Benjamin Franklin, this instrument uses rotating glass bowls. Musicians create haunting tones by rubbing their fingers around the glass, producing an almost supernatural sound. Did you know about this as one of the crazy instruments?
Theremin
One of the strangest electronic instruments, the theremin is played without physically touching it. Moving your hands around two antennas controls pitch and volume.
Ondes Martenot
This early electronic instrument from France can produce eerie, sliding tones. It has been used in classical music and film scores, particularly when composers wanted an otherworldly sound.
Hang
The Hang resembles a metallic UFO or unusually shaped steel drum. Players tap and strike different sections with their hands to create melodic, resonant sounds.
Octobass 
This enormous bowed string instrument is so tall that it towers over most musicians. Its extremely low notes can reach frequencies that are felt almost as much as they are heard. Did you know about this as one of the crazy instruments?
Nyckelharpa
A traditional Swedish instrument that looks like a cross between a violin and a keyboard. It has strings played with a bow, while keys control additional strings and notes.
Serpent
Despite its name, this historical wind instrument isn’t an animal. Its long, curved wooden body resembles a giant snake, while its deep sound sits somewhere between a brass and woodwind instrument.
Subcontrabass Recorder
This enormous relative of the recorder produces extremely low notes. Some versions are so large that players need unusual finger positions and considerable physical coordination.
Musical Saw
A regular handsaw can become an instrument when bent and bowed correctly. The resulting sound is remarkably smooth and ghostly, making it popular for unusual musical effects. Did you know about this as one of the crazy instruments?
Cimbalom
This Hungarian instrument looks like a large trapezoidal table covered in strings. Players strike the strings with small beaters, producing a shimmering mixture of piano, harp, and percussion-like sounds.
Didgeridoo
Traditionally associated with Aboriginal Australian musical cultures, the didgeridoo is a long wind instrument capable of producing deep drones and complex rhythmic effects. Skilled players can use circular breathing to sustain sound for remarkably long periods.
Waterphone
This bizarre percussion instrument consists of a metal resonator with rods of different lengths. When struck or bowed, it creates eerie, unpredictable tones that have famously appeared in horror and thriller soundtracks.
Musical Bicycle
Some experimental musicians have transformed bicycles into instruments by using wheels, spokes, frames, and other components to create rhythms and tones. Did you know about this as one of the crazy instruments?
Contrabassoon
The enormous contrabassoon is essentially the giant, deep-voiced relative of the bassoon. Its low, rumbling sound can make an orchestra sound dramatically darker.
Daxophone
A wooden strip mounted on a resonating box, the daxophone produces bizarre animal-like voices when rubbed or bowed. Different pieces of wood create radically different sounds.
Carillon
A carillon is a massive set of tuned bells housed in a tower. Instead of being played like ordinary bells, the instruments can be operated from a keyboard and can produce surprisingly complex melodies.
Glass Harp
Similar in principle to the glass armonica, a glass harp uses individual glasses filled with different amounts of water. Musicians rub the rims with wet fingers to produce musical notes. Did you know about this as one of the crazy instruments?
Musical Stones
Certain rocks can be carefully selected and tuned so that striking them produces distinct musical pitches. Some ancient and modern stone instruments consist of entire collections of resonant rocks.
