Serra and the team used “complex algorithms” to process pop music from the last 55 years (1955-2010) – from Elvis to Lady Gaga. To do this, they used the Million Song Dataset, a “freely-available collection of audio features and metadata for a million contemporary popular music tracks,” whose purpose is to aid in research projects just like this one.
“We found evidence of a progressive homogenization of the musical discourse,” Serra told Reuters. “In particular, we obtained numerical indicators that the diversity of transitions between note combinations – roughly speaking chords plus melodies – has consistently diminished in the last 50 years.”
