"To get closer to the truth, however, the team brought in professional rock singer Daniel Zangger-Borch to imitate Mercury’s voice. They filmed his larynx at 4,000 frames per second in order to look at exactly how the Queen frontman created those iconic rough growls and jaw-dropping vibratos. What they discovered was that he likely employed subharmonics, a singing style where the ventricular folds vibrate along with the vocal folds. Most humans never speak or sing with their ventricular folds unless they’re Tuvan throat singers, so the fact that this popular rock vocalist was probably dealing with subharmonics is pretty incredible."
