Vocal pressure

The Miracle of Producing a Large Pitch Range (Article)
The development of vocal fold tissues to accommodate vibration over large pitch ranges is nothing short of a miracle. An experiment (which cannot be performed) would be to expose one vocal fold of a human being to normal daily vibration from birth to adulthood while preventing the other vocal fold from vibrating at all. We could then answer questions about whether such specialized tissue development is driven purely by the applied forces or partly by genetics. (posted 2:34 PM, August 27, 2014)
