TL;DR: The flute is almost certainly the oldest musical instrument in human history -- a bone flute found in Slovenia is estimated to be between 40,000 and 60,000 years old, predating drums and all other known instruments. Despite that ancient lineage, the modern concert flute's key mechanism was still being refined well into the 20th century, when French inventor Djalma Julliot filed a U.S. patent in 1908 for an improved key arrangement. Original prints of that patent are available framed or unframed.
The oldest musical instrument ever found is a flute. It was discovered in the Divje Babe cave in what is now Slovenia, carved from the femur of a cave bear, and researchers estimate it is somewhere between 40,000 and 60,000 years old. The being who made it was almost certainly a Neanderthal. The flute did not come after music. In the archaeological record, it essentially is music.
That an instrument of that lineage would still be receiving engineering patents in the early 20th century is one of the more surprising continuities in the history of technology. Djalma Julliot of La Couture-Boussey, France filed a U.S. patent in 1908 for a novel arrangement of flute keys that made the instrument easier to operate. The flute had been played for 60,000 years. It was still being invented.
The Oldest Known Instruments: Neanderthal Flutes
The Divje Babe flute, housed today at the National Museum of Slovenia in Ljubljana, represents one of the most consequential archaeological finds in the study of human prehistory. The bone has holes that align in a pattern consistent with a deliberate musical scale, and the spacing and symmetry of those holes are difficult to explain as accidental damage. Most researchers now accept the object as an intentional instrument.
A second ancient flute, recovered from the Hohle Fels cave in Germany, dates to approximately 35,000 years ago and was made from a vulture wing bone. This instrument had five finger holes and a V-shaped mouthpiece -- a design sophisticated enough that it clearly reflects accumulated knowledge about how to produce a range of pitches from a single bone tube. A related flute from the same site was made from mammoth ivory, which required splitting the ivory lengthwise, carving the interior, and rejoining the pieces: a manufacturing process more complex than anything required to make a bow or a spear point.
The implication is significant. These early humans were not simply responding to the physical world. They were creating organized sound for purposes that went beyond communication or tool use. The flute is evidence of abstract thinking, cultural transmission, and a recognition that certain arrangements of pitch produce experiences worth repeating and sharing.
Ancient Flutes Across Civilizations
The flute did not remain confined to Paleolithic Europe. Several bone flutes discovered in Jiahu, in Henan province in central China, date to approximately 9,000 years ago. These instruments, made from the wing bones of the red-crowned crane, had between five and eight holes and were tuned to specific scales. Some of the Jiahu flutes are still playable today, and recordings of them demonstrate that they were capable of producing a recognizable diatonic scale.
Flutes appear in ancient Mesopotamia, in the Indus Valley civilization, and in Egypt, where transverse flutes -- held horizontally rather than pointed downward -- appear in wall paintings from around 3000 BC. The spread of the instrument across independent cultures suggests either very early diffusion from a common origin or independent invention across multiple populations who arrived at similar design solutions.
In ancient Greece, the flute held a complicated status. The aulos, a reed instrument related to the oboe, was more prominent than the true flute in Greek musical culture, but wind instruments generally were associated with the emotions and with popular entertainment rather than with the intellectual rigor attributed to the lyre. Aristotle observed that the flute was unsuitable for education because it did not develop the mind. The flute was the instrument of festivals, of Dionysian celebration, of the commons -- which contributed to its widespread popularity and, paradoxically, to its undervaluation in the formal record.
The Medieval Rediscovery and Military Use
After the fall of Rome in the 5th century AD, documentation of flute playing in Europe largely disappears from the historical record. The instrument did not vanish -- folk practice rarely leaves written evidence -- but its presence in formal musical documentation does not reappear with clarity until the 10th and 11th centuries.
When the flute re-emerged in the European written record, it was often in a military context. The transverse flute, the horizontal design that is the direct ancestor of the modern concert flute, was associated with military campaigns by the 11th and 12th centuries. Its high, penetrating tone made it effective as a signaling instrument on the battlefield, where drummers and fifers communicated orders across the noise of combat.
The fife, a small transverse flute pitched higher than the standard instrument, became a fixture of European military music from the 14th century onward. Swiss and German mercenary armies carried fifers alongside drummers, and the fife-and-drum corps became a standard element of military organization across Europe. The instrument was essentially a tool of command and coordination, and its musical qualities were secondary to its acoustic carrying power.
This military role had a curious effect on flute design: it kept the instrument simple and robust. A battlefield fife needed to function under harsh conditions, and elaborate mechanism was a liability. The ornate, multi-key concert flutes of later centuries would have been useless in the field.
The Baroque Transformation and Bach
The 17th century began a transformation in the flute's design and status. European instrument makers, particularly in France and Germany, began modifying the simple cylindrical bore of the medieval flute, introducing a conical bore that improved tone quality and intonation. The instrument was also divided into multiple sections -- typically three -- which made it more portable and allowed for greater manufacturing precision in each component.
Johann Sebastian Bach was central to establishing the flute as a serious concert instrument. His sonatas and chamber works written for the transverse flute treated it as a fully capable melodic voice rather than a decorative element, and his advocacy brought the instrument into the repertoire of professional musicians across Europe. The Baroque flute -- particularly the one-key design associated with the Hotteterre family of French instrument makers -- became the standard for concert performance through much of the 18th century.
The sonatas Bach wrote for the instrument, including the Sonata in B minor BWV 1030, remain among the most technically demanding pieces in the flute repertoire. They were written for an instrument with one key and six finger holes, requiring the performer to use half-holing and embouchure adjustments to achieve notes that later instruments would produce with additional keys.
The Boehm System and the Path to the Patent
The critical mechanical transformation of the concert flute came in the 19th century through the work of Theobald Boehm, a Bavarian goldsmith, flutist, and engineer. Boehm's fundamental insight was that the tone holes on a flute should be placed at acoustically optimal positions for the physics of the instrument, not at positions convenient for the human hand. The two had never previously been the same place.
To solve the resulting mechanical challenge -- how to allow the fingers to cover holes placed beyond their natural reach -- Boehm developed a ring-and-axle key system that allowed one finger movement to close multiple holes simultaneously. His 1847 design established the cylindrical bore and key arrangement that is the basis of virtually every concert flute made today.
The Boehm system was a profound re-engineering of an instrument that had existed for tens of thousands of years. It replaced centuries of accumulated folk knowledge about fingering technique with a systematic mechanical solution derived from acoustic principles. For professional musicians, the transition was not painless: the Boehm fingering system required relearning skills that had taken years to develop on the older instruments.
It was within this framework of ongoing mechanical refinement that Djalma Julliot of La Couture-Boussey -- a town in Normandy that had been a center of French wind instrument manufacturing since the 17th century -- filed a U.S. patent in 1908. His patent addressed the arrangement and combination of keys in a way that simplified operation for the player, building on the Boehm foundation while finding new ways to reduce technical complexity. This was one of two U.S. patents he was granted, though his work in France was more extensive. The drawing he submitted to the U.S. Patent Office is a precise record of that continued engineering effort, decades after the Boehm revolution and millennia after the first bone flute was played in a Slovenian cave.

Frequently Asked Questions
What is the oldest flute ever found?
The Divje Babe flute, found in Slovenia, is estimated to be between 40,000 and 60,000 years old and is believed to have been made by Neanderthals from a cave bear femur. It is the oldest known musical instrument ever discovered. A second ancient flute from the Hohle Fels cave in Germany dates to approximately 35,000 years ago and was made from a vulture wing bone with five finger holes.
Who invented the modern concert flute?
Theobald Boehm, a Bavarian goldsmith and flutist, designed the key system that forms the basis of the modern concert flute in 1847. His innovation placed tone holes at acoustically optimal positions rather than where fingers naturally rested, and his ring-and-axle mechanism solved the resulting technical challenge. Virtually every concert flute made today is based on the Boehm system.
Who filed the 1908 flute patent?
Djalma Julliot of La Couture-Boussey, France filed a U.S. patent for a flute design in 1908. His patent covered a novel arrangement and combination of flute keys that made the instrument easier to operate for players. He was granted two U.S. patents and filed additional patents in France. La Couture-Boussey had been a center of French wind instrument manufacturing since the 17th century.
When did the flute become a military instrument?
The transverse flute became associated with European military use by the 11th and 12th centuries, used for battlefield signaling and march coordination alongside drums. The fife, a small high-pitched version of the transverse flute, became a fixture of European military music from the 14th century onward. Swiss and German mercenary armies were particularly associated with fife-and-drum corps, and the tradition spread across Europe through the early modern period.
