उत्तर

A different sound is produced when the frequency of vibration of the source of sound is changed. In humans, vocal cords in the larynx vibrate and produce sound. Now, the frequency of vibration of vocal cords is directly dependent on the tension produced on it. The higher the tension on the chords, the shriller will be the voice produced. So, we can say that it is essential to change the tension on the vocal cords to produce different sound notes from our larynx.
