Western pop music

A research team looked at more than 17,000 songs from the US Billboard Hot 100 and found three music revolutions - in 1964, 1983, and 1991.

The researchers looked at the different characteristics of music, including harmony, chords changes, and timbres, then analyzed how they changed over time.

Stylistic revolutions

Stylistic revolutions

  • In the 1960s, the radical new rocky sound emerged from the Beatles to the Rolling Stones.
  • The minor seventh chords were introduced through funk, soul, and disco in the 1970s.
  • In the 1980s, there was a blip where the introduction of arena rock meant that music lacked diversity.
  • New technology, synthesizers, samplers, and drum machines marked the second major style shift in 1983.
  • In 1991, rap and hip-hop went mainstream. This revolution doesn't use a lot of harmonies. Emphasis is on speech sounds and rhythm.

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!

I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!
