During regular archaeological excavations, several flutes that date to the European Upper Paleolithic have been discovered in caves in the Swabian Alb region of Germany. Dated and tested independently by two laboratories, in England and Germany, the artifacts are authentic products of the Homo sapiens Aurignacian archaeological culture, made in between 43,000 and 35,000 years ago. The flutes, made of bone and ivory, represent the earliest known musical instruments and provide unmistakable evidence of prehistoric music.
The flutes were found in the Caves with the oldest Ice Age art, where also the oldest known examples of figurative art were discovered. Music and sculpture as artistic expression have developed simultaneously among the first humans in Europe, as the region is considered a key area in which various cultural innovations have developed. Experts say, besides serving recreation and religious purposes, ritual music might have helped to maintain larger social networks, a competitive advantage over the Neanderthals.
In 2006, the Hohle Fels Flute was discovered in the Hohle Fels cave in Germany's Swabian Alb. The flute is made from a vulture radius bone perforated with five finger holes, and dates to approximately 35,000 years ago. Several years before, two flutes made of mute swan bone and one made of woolly mammoth ivory were found in the nearby Geissenklösterle cave. The team that made the Hohle Fels discovery wrote that these finds were, at the time, the earliest evidence of humans being engaged in musical culture. They suggested music may have helped to maintain bonds between larger groups of humans, and that this may have helped the species to expand both in numbers and in geographical range. In 2012, a fresh high-resolution carbon dating examination revealed an age of 42,000 to 43,000 years for the flutes from the Geissenklösterle cave, suggesting that they rather than the one from the Hohle Fels cave could be the oldest known musical instruments.
The artifact known as the Divje Babe flute, discovered in Slovenia in 1995, has been claimed as the oldest flute, though this has been disputed. The artifact is a cave bear femur, 43100 ± 700 years old, that has been pierced with spaced holes. Its discoverer suggested the holes were man made and that there may have been four originally before the item was damaged. However, other scientists have argued that the holes were chewed by an animal.
