Study Reveals Simplification of Pop Melodies Over Seven Decades

Research shows a trend towards simpler, more repetitive melodies in top-charting songs since 1950, with significant shifts in 1975 and 2000.

Analysis of over 1,000 Billboard chart-toppers indicates a decrease in melodic complexity and an increase in note density.
Two major 'melodic revolutions' identified: one in 1975 and another in 2000, linked to disco and hip hop influences.
Modern pop songs use fewer notes and simpler rhythms but deliver melodies more rapidly, creating energetic tunes.
Researchers suggest the evolution may be driven by changes in music production and consumption habits.
The study highlights the growing formulaic nature of pop songwriting, with little evidence of retro trends.
