Archaeologists commit a good deal of time inspecting the remains of distant pasts, which consists of the research of rock paintings. This is mainly visible function – but sometimes we can “hear” the ancient past employing acoustic procedures.
Our archaeoacoustic investigate is concentrated on bringing to life sounds manufactured by folks living in the previous. No aural record stays but persons did dance, sing and clap. Devices possibly no lengthier exist or are very rare. One exception are the gong rocks, known as lithophones, which ring when struck and generate purposeful, percussive sounds. From time to time, unfamiliar and exceptional musical devices are depicted in rock paintings.
In a new review we turned our ears to a rock portray in the Cederberg Mountains in South Africa’s Western Cape province. The human figures in this portray have formerly been interpreted as healers keeping fly-whisks and doing a trance-dance. Fly-whisks were being an vital accent for the dance for the reason that they had been believed to maintain arrows of illness at bay.
But our final results counsel that the fly-whisks are in actuality musical instruments of a kind known as a !goin !goin – a name that only exists in the now extinct ǀXam language that was spoken by hunter-gatherers in central southern Africa. The !goin !goin is an aerophone these instruments create audio by creating vibrations in the air when they are spun about their axes.
To reach this summary we blended digital graphic recovery techniques with devices developed from lifetime-size templates dependent on our findings. The eight instruments have been played in a Cape City sound studio and the seems have been recorded. Seem created by the recreated devices convincingly matches the audio spectrum (90 – 150 Hz) created by a identical 19th century design of the !goin !goin aerophone, which is archived in the Kirby Collection of Musical Instruments, curated by the College of Cape Town’s Faculty of Songs.
Our success suggest that !goin !goin form aerophones were used around or just before 2000 a long time back. This summary is based on the age of the impression that is painted in the high-quality-line procedure, which is a type of painting that disappeared with the arrival of pastoralists in the southern Africa location 2000 a long time back.
The Cederberg painting is one of only 4 identified illustrations of aerophone taking part in depicted in rock paintings in the southern Africa area. By distinction lots of paintings are identified as illustrating fly-whisks. Our results propose the want for bigger nuance when studying rock paintings. Potentially some of the fly-whisk depictions should be revisited with a “listening ear”?
The !goin !goin generates a distinctive pulsating audio (visualised in the picture under) due to the circular rotation of the player’s arm and the twisting and untwisting of the wire that attaches the rotating blade to the stick.

An unanticipated locating was the compositional alternatives supplied when two or far more !goin !goin were being played at the exact time. Dashing up and slowing down the rotation subtly adjustments the seem. Two devices, one particular played rapidly and the other sluggish, creates a composition. Taking part in in sync and out of sync adds a different layer of musical generation.
It was not doable to perform 8 instruments in the audio studio at a person time. An 8-instrument general performance requires much more room than the studio could provide. But a seem recording of three !goin !goin taking part in collectively implies what team songs-generating with the !goin !goin might have sounded like.
This compositional factor of the instrument was not very well recognised at all so we delved deeper. In the Distinctive Collections archive at the University of Cape Town we discovered an obscure description of the !goin !goin which confirmed, as does the Cederberg painting, that groups did participate in the devices alongside one another.
An instrument consisting of a blade of wooden hooked up to a little stick, which is held in the hand. The performer greedy the minor stick whirls the blade about in the air, making a whirring seem. It is used by equally sexes among the Bushmen [another name used for the San and today considered derogatory by some] and, at instances, by a quantity of folks with each other with the look at to creating rain.
ǀXam-talking hunter gatherers related the seem of the !goin !goin with honey bees. They even went so much as to say that with the !goin !goin they could “move bees”. This enhances the past assertion linking the instrument’s seem with “causing rain”. The archive statement also confirms that both equally gentlemen and females worked with rain, making use of the audio of the !goin !goin for this reason.
What archaeology tells us about the audio and seems produced by Africa’s ancestors
What of the trance therapeutic dance advised by earlier interpretations of the Cederberg portray? It is very well acknowledged that all senses, not just eyesight, hallucinate in trance and that the aural hallucination of buzzing is construed as the seem of bees, rushing wind or slipping water. So the painting does website link to trance because of the affiliation with bees and buzzing – but the merchandise depicted in the portray are musical devices, not fly-whisks.
