Overview
This is the secret to "thick" modern vocals. Instead of creating a harmony (which adds a new melody), you simply reinforce the existing one. A Low Octave adds "weight" and a moody, "god-like" authority (think Travis Scott or Billie Eilish). A High Octave adds "shimmer," "air," and excitement (common in Pop and R&B). It’s the ultimate way to make a chorus feel "important" without making it sound cluttered.
