Vocal folds video of the voice in action
I was introduced to this vocal folds video by another singing teacher as it shows what happens to the voice as a student sings higher and higher. Note how the vocal cords get stretched longer and longer gradually as the pitch ascends. Though you can’t see it, the vocal cords are also getting thinner in depth to allow for the change in pitch to be continue.
I found this video to be an eye-opening experience to how icky the inside of the human voice looks, but how it generates such a beautiful sound. Check it out! If you have any questions about this, leave a comment and I’m happy to chip in if I can help.
