How Polyphonic Singing Works
In How Polyphonic Singing Works, explore the fascinating phenomenon of polyphonic singing. The video features Wolfgang, a singer who can produce two notes at once. Using an MRI, Wolfgang and researchers uncover the mechanics behind this rare ability, revealing how changes in the shape of the tongue and larynx allow the vocal apparatus to create distinct tones simultaneously. This video is excerpted from BBC’s The World’s Most Extraordinary People, a documentary series revealing how rare medical conditions inspire groundbreaking scientific discoveries.
Lesson Express
Q: What is polyphonic singing, and how does it differ from regular singing?
A: Polyphonic singing involves producing multiple notes at the same time. It differs from regular singing, which typically produces only one note at a time.
Q: What did the MRI show about Wolfgang’s tongue position when producing overtones?
A: The MRI showed that Wolfgang’s tongue moves to create pockets of air in his mouth, which allows him to produce multiple tones simultaneously.
Q: Why is polyphonic singing considered an extraordinary ability?
A: It is rare because most people can only produce one note at a time, whereas polyphonic singing requires the ability to manipulate the vocal tract to produce two or more sounds simultaneously.
