The vocal cords (or vocal folds) are two pairs of membranes stretched across the larynx, the thicker pair protecting the thinner pair, which may be pulled tight to produce sound through vibration as air is passed between them. Their tension may be finely controlled in order to produce sounds of varying pitch, and can be closed together completely to hold your breath. While not being used for these purposes, they remain relaxed and open to allow breathing. The true focal folds are protected by a second pair of ' false folds'. These secondary, thicker folds play a much smaller part in producing sound, principally when producing deep, low sounds.
they vibrate
Sound is produced. Vocal cords vibrate and produce sound.
Sound. Vibrating vocal cords produce sound. The speed at which they vibrate determines whether the sound is high pitched or low pitched.
By vibrating
you have vocal cords to produce your voice
vocal cords
to produce vocal sounds you have to keep singing but try not to sing to much that you strain your vocal sound to much so that you cant sing any more that happened to me
When they are close together, that means that they will produce sound. To change pitch is another mechanism entirely; which involves both stretching and bulking the vocal folds (vocal cords).
The same way we talk, the vibrations of our vocal cords produce sound.
they don't sing like male frogs do if that's what you're asking
Giraffes have no vocal cords, hence they do not make any sound.
The vocal cords, when you talk or sing, chop the air coming out of you lungs. If you want the sound to be higher, the vocal cords will tighten. When you want the sound to be deeper, the vocal cords will relax. If you want more information, go onto YouTube and search "Vocal Cords".
Your vocal cords - are two strips of skin located at the top of the larynx. When air passes over them, they vibrate - combined with the shape of your mouth, and breathing method - they produce sound.
