1. Why Some People Can Sing and Some Can’t: How Their Vocal Cords Change Name: Rida Zainab, Saman Sohail Mina Tara Group: 1 Semester: 8

2. Introduction Some people naturally have a good singing voice, while others struggle to carry a tune. This difference is due to a combination of genetics, vocal cord anatomy, training, and health. This presentation explores how vocal cords contribute to singing ability.

3. Anatomy of the Vocal Cords • Vocal cords (vocal folds) are two flexible bands of muscle in the larynx. • They vibrate to produce sound when air passes through. • Length, tension, and thickness of vocal cords determine pitch and tone.

4. How Sound is Produced in the Larynx • Air from the lungs passes through the glottis, making the vocal cords vibrate. • The vibration frequency determines pitch (higher frequency = higher pitch). • Resonance in the throat, mouth, and nasal cavity affects tone quality.

5. Role of Genetics in Singing Ability • Genetics influence vocal cord size, shape, and flexibility. • Some people inherit a more favorable vocal anatomy for singing. • Musical perception (pitch recognition) also has a genetic component.

6. Training vs. Natural Talent • Natural singers often have well-coordinated vocal muscles. • Training can improve vocal technique, range, and tone. • Proper breathing and vocal exercises can enhance anyone’s singing ability.

7. Physiological Differences in Vocal Cords • Thinner, more flexible vocal cords can produce higher pitches. • Thicker cords produce deeper tones. • Muscle control and elasticity affect vocal range and quality.

8. Impact of Vocal Cord Health on Singing • Hydration keeps vocal cords flexible and prevents strain. • Smoking and acid reflux can damage vocal folds. • Overuse or misuse can lead to vocal fatigue and hoarseness.

9. Common Vocal Cord Disorders Affecting Singing • Vocal nodules: Calluses that form due to strain. • Polyps: Swollen growths that affect voice quality. • Laryngitis: Inflammation leading to temporary voice loss.

10. Conclusion • Singing ability is influenced by genetics, vocal anatomy, training, and health. • While some are naturally gifted, vocal training can improve singing skills. • Maintaining vocal health is essential for optimal voice quality.
