Detailed explanation-1: -If the vocal chord is tight and thin, it will produce a high frequency sound or you can say that it will produce high pitch sound as pitch of the sound directly depends on the frequency of the sound. A thick and loose vocal chord will produce the sound of low frequency or low pitch.

Detailed explanation-2: -When the heavy muscle that shortens and thickens the vocal folds is active, a larger bulk of the folds is active in vibration. This affects the quality of the sound. For lower notes, the folds vibrate slower and therefore can remain shorter and thicker. For higher notes, the folds vibrate faster.

Detailed explanation-3: -Vocal Fold Vibration & Pitch Extremely slow vocal fold vibration is about 60 vibrations per second and produces a low pitch. Extremely fast vocal fold vibration approaches 2000 vibrations per second and produces a very high pitch. Only children and the highest sopranos can attain those extremely high pitches.

Detailed explanation-4: -The fundamental frequency is influenced by the length, size, and tension of the vocal folds. This frequency averages about 125 Hz in an adult male, 210 Hz in adult females, and over 300 Hz in children.
