When the vocal cords are stretched tightly, what type of sound is produced?
A
low pitch
B
high pitch
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -When our vocal cords are thin and stretched, the muscles attached to vocal cords contract and hence, a sound of high frequency is produced. It also implies that the of the sound produced is very high. Similarly, when the vocal cord is thick and loose, a lower-frequency sound will be produced.

Detailed explanation-2: -Strained vocal cord symptoms may include: Chronic hoarseness for more than two weeks (such as a raspy or breathy voice, a voice quiver, or a strained or choppy voice) Pain or a lump in the throat when speaking. Changes in pitch.

Detailed explanation-3: -Contraction of the CT muscle stretches and increases the tension of the vocal folds, causing them to vibrate at a higher F0 and raising the pitch of the voice [9–13].

Detailed explanation-4: -Vocal Fold Vibration & Pitch Notice that every time you go up an octave, you double the frequency of vibration. The faster the vocal folds vibrate, the higher the pitch. Extremely slow vocal fold vibration is about 60 vibrations per second and produces a low pitch.
