A lot of ideas taken from science play a part in vocal fold vibration. Both the Myoelastic Aerodynamic Theory and Bernoulli Effect deal with pressure and help to explain how vocal folds operate to create phonation. These processes can also be applied to real-life situations.
The Myoelastic-Aerodynamic Theory describes the process of vocal fold vibration. It is important to recognize that the vibration of the vocal folds is the result of the interaction between tissue properties and airflow, not repetitive muscle contraction. To begin the process, the vocal folds are adducted, meaning being pulled close, to the midline with the Lateral Cricoarytenoid, Thyroarytenoid, and Interarytenoid muscles. The contraction of these muscles is constant throughout …show more content…
This information helps understand how someone can create sound, which leads to the topic of how sounds can be adjusted from different properties. In Case Two, it mentions how amazing Mariah Carey’s voice is as she demonstrates clear voice quality, as well as changes in pitch and loudness. This is because of the differences in mass, length, and tension. Vocal folds with more mass have a lower pitch while those with lower mass have a higher pitch. In addition, longer vocal folds have a lower pitch while those with shorter vocal folds have a higher pitch. It is mentioned how in Mariah Carey’s song “Emotions” we hear her sing in her lowest range, her falsetto, and her whistle register, this is because she is able to stretch her vocal folds to different amounts of tension creating a range of pitches. As a result, vocal folds with more tension will have a higher pitch while those with less tension will have a lower pitch. There are 3 different vocal registers; Modal Register, Falsetto, and Glottal Fry. Modal Register is the normal pitch that uses the cover and part of the body layers of the vocal folds. The vocal folds vibrate normally during this modal register, and the pitch is at a comfortable level. In addition, a falsetto register causes vocal fold vibration of the cover layers and produces a pitch at the highest end of the individual’s vocal range. Finally, glottal fry is the lowest end of the pitch range. Both the cover and body layers of the vocal folds are used. The vocal folds are very relaxed and cause the vocal folds vibrate very slowly, thus creating this low
