Vertical complexity is a very strong element in musical storytelling because it channels your audience's attention! We go into what that means way deeper inside the Academy but for now, let's just talk about the concept you can use to control vertical complexity in your compositions.
Once you know the register where most of the action takes place, spot the empty spots and "extend the intervals" into these registers.
And this step can be part of the sketch, as it's very quick and easy to apply. You should try it, and if you write a great composition using that technique, I'd love to hear it! So, please let me know!
