“Well, we’re all in the mood for a melody,” Billy Joel crooned in “Piano Man,” his iconic 1973 barroom ballad. That may have been true enough when Mr. Joel wore a younger man’s clothes, but a new study conducted by computational musicologists at Queen Mary University of London has found that vocal melodies in popular music have become much less complex over time.
The study, published on Thursday in the journal Scientific Reports, used mathematical models and algorithms to pinpoint three “melodic revolutions” — in 1975, 1996 and 2000 — that brought increasing simplicity to the two main components of melody: rhythm, or the pattern of sounds and silences in a piece of music, and pitch, the measure of how high or low the notes are.
The study looked at the top five Billboard songs every year from 1950 to 2023. Both rhythm and pitch became steadily less complex over that period, the study found. “Conservatively, they have both decreased by 30 percent,” said Madeline Hamilton, a graduate student at Queen Mary University of London who led the research.
The 1975 hit “Love Will Keep Us Together” by Captain & Tennille contains a lot of unexpected notes and rhythmic complexity.
“Breathe” by Faith Hill, the top song of 2000, has no accidentals, lots of repetition and straightforward rhythms.
