Mix with your song structure in mind
There are standard tricks a mixing engineer can call on to cater to and complement the song structure and arrangement and create a great overall mix.
A great song is not static: it grows, contracts, and changes from intro to ending to keep the listener engaged and create an emotional connection. By its very nature, music is dynamic, full of life and emotion, and an expert arrangement and mix should contribute to that.
When listening to an album or collection of songs that are mastered and mixed well, one characteristic the songs might have in common is a shift in energy from one section to the next. It’s typical that the feel of a song will change as it shifts from a verse to a chorus or a chorus to a bridge.
