TED-Ed: What’s a squillo, and why do opera singers need it?

The video explores how opera singers project their voices over an orchestra without microphones. It delves into the physics of sound, explaining how vibrations create sound waves and how harmonics and overtones contribute to the unique sound of each instrument. The video highlights the techniques opera singers use to emphasize certain frequencies, creating a powerful projection known as 'squillo'. It also discusses the role of biology and physical preparation in achieving these vocal feats, emphasizing the importance of lung capacity, posture, and vibrato.
