At first glance, ambient music often appears simple.
Few notes.
Few elements.
Slow movement.
However, simplicity can create its own form of complexity.
When there are only a handful of sounds present, each small change becomes significant.
A subtle adjustment in timing.
A slight shift in volume.
The introduction or removal of a single layer.
These events might go unnoticed in a dense arrangement.
In a sparse environment, they become structural.
