Happy Music Isn’t Popular Anymore
Lyrics and instrumentation aside, there are two primary differences between happy songs and sad songs. Happy songs are uptempo and in a major key. Sad songs tend to be slower and in a minor key. In 1965 every one of Billboard’s top 40 hits were in a major key. Today, a majority of popular songs are in a minor key. Why is that?
