"If you were to trace a line that represents the energy you perceive from a song as it progresses, you’d notice that the line would generally go in a mostly-upward direction. That’s a basic songwriting principle: the energy of the end of a song should equal or exceed that of the beginning. It’s that sense of intensifying energy and forward motion that keeps listeners listening. In particular, the chorus needs to take whatever the energy level is in the verse and pump it up a bit.
When you think about “energy”, you might tend to think about things getting faster, but that rarely happens in music. Especially in pop music genres, tempos are set at the beginning, and they stay pretty much constant.
So what are the things you can do in your song to ensure that the energy your listeners get from your chorus is more than what they get from the verse? Here are 7 ideas."
