The impact of hip-hop cannot be under-estimated, said music journalist Dorian Lynskey. “What we can’t do with a computer is understand the meaning of the music to us,” he said. “We will be able to reconstruct the history of art and develop a mathematical theory of its evolution, just as scientists have done for the history of life,” Leroi said.īut he acknowledges there are some aspects of culture that the technology can’t reach – at least for now. People are already applying similar methods to digitized books, he said, and paintings are also likely to be fair game through image recognition technology. Leroi said he expects this study – which he worked on with Matthias Mauch from Queen Mary University of London – to be the first of many in an emerging field examining the evolution of different cultures through data. The low point for variety was in the early 1980s, when genres like new wave, disco and hard rock dominated.The researchers said they found “no evidence for the progressive homogenization of music in the charts.” Although many people complain that pop music has gotten more and more samey, diversity actually increased in the ’80s and ‘90s as hip-hop emerged and flourished.The researchers took 30-second clips of each song and broke them down into topics relating to harmony and timbre, like “major chords without changes” and “guitar, loud, energetic.” To gather that evidence, they used music recognition technology – similar to what’s in the apps SoundHound and Shazam – to analyze more than 17,000 songs that made up 86% of the U.S. “We had a sense that lots of people have opinions about popular music, but nobody has any objective evidence,” said Armand Leroi, one of the study’s authors. In a study published Wednesday in the journal Royal Society Open Science, the researchers say they threw out “musical lore and aesthetic judgment” in favor of scientific rigor. That’s not an opinion, it’s fact – backed up by hard data, says a team of researchers from two London universities. Forget The Beatles and The Rolling Stones, the most important development in pop music in the past half century is hip-hop.
