Vijftig jaar geleden: Pier-Luigi Tagliavini wint de eerste Rapport Toer
De Rapport Toer is de oudste meerdaagse wielerwedstrijd in Zuid-Afrika. Ze werd voor het eerst betwist in 1973, maar alhoewel Cycling Archives vrij gedetailleerde informatie geeft, kom ik toch niet te weten op welke datum ze precies is aangekomen. De eerste winnaar was de onbekende Italiaan Pier-Luigi Tagliavini, wellicht op 12 oktober. In 2000 was het afgelopen met de Rapport Toer, maar toen was…

In the 1980s in France, musicologists and archaeologists Iégor Reznikoff and Michel Dauvois used their voices to explore caves with notable Paleolithic wall paintings. By singing simple notes and whistling, they mapped their perceptions of the caves’ acoustics.
They found that paintings were often located in places that were particularly resonant. Animal paintings were common in resonant chambers and in places along the walls that produced strong reverberation.
As they crawled through narrow tunnels, they discovered painted red dots exactly located in the most resonant places. The entrances to these tunnels were also marked with paintings. Resonant recesses in walls were especially heavily ornamented.
In a 2017 study, a dozen acousticians, archaeologists, and musicians measured the sonic qualities of cave interiors in northern Spain. The team, led by acoustic scientist Bruno Fazenda, used speakers, computers, and microphone arrays to measure the behavior of precisely calibrated tones within the cave.
The caves they studied contain wall art spanning much of the Paleolithic, dating from about forty thousand years to fifteen thousand years ago. The art includes handprints, abstract points and lines, and a bestiary of Paleolithic animals including birds, fish, horses, bovids, reindeer, bear, ibex, cetaceans, and humanlike figures.
From hundreds of standardized measurements, the team found that painted red dots and lines, the oldest wall markings, are associated with parts of the cave where low frequencies resonate and sonic clarity is high due to modest reverberation.
These would have been excellent places for speech and more complex forms of music, not muddied by excessive reverberation. Animal paintings and handprints were also likely to be in places where clarity is high and overall reverberation is low but with a good low-frequency response.
These are the qualities that we seek now in modern performance spaces.
