I love the idea of subtle modulation. I wanted to, over the course of a minute or so of music, try to get to a distant key from the starting one without huge bumps along the way. Something that settles at the end, but you don’t realize how far you’ve traveled from the home key until you replay the beginning. I think the tools that really helped me accomplish this here was the left hand pattern as well as the lack of a real melody. It’s just textural flourishes. It distracts the brain from what’s really going on.
