Why do trained male singers cut through orchestras effortlessly while you're straining to be heard over a single guitar? The answer isn't talent—it's acoustic physics.
In Part 1 of our 5-episode Formant Series, we break down the singer's formant: a learnable concentration of acoustic energy around 3,000 Hz that gives low voices their characteristic ring and carrying power. You'll learn what creates this physiologically (hint: pharynx width + epilaryngeal narrowing), why this frequency region exploits a built-in perceptual advantage, and how to develop it in your own voice.
We also tackle the passaggio—that stuck, heavy feeling around E4-G4—with the acoustic explanation for what "covering" actually means and practical strategies for navigating the transition smoothly.
