As a music lover it's fun to try to figure out why one song, or any song is a hit. What makes it jump out at you. Guitar licks, a blazing piano, emotive lyrics or in the case of this article a key change.
"In fact, 23 percent of number one hits between 1958 and 1990 were in multiple keys."
"The act of shifting a song’s key up either a half step or a whole step (i.e. one or two notes on the keyboard) near the end of the song, was the most popular key change for decades. In fact, 52 percent of key changes found in number one hits between 1958 and 1990 employ this change."
"What’s odd is that after 1990, key changes are employed much less frequently, if at all, in number one hits."
An interesting article.....
