Purpose The purpose of this experiment is to see if there is an affect on your vocal pitch when you drink certain liquids. If you can match that pitch on the piano keyboard, then that liquid is good for you before you sing. Background Information Have you ever sung a song and realized while you were singing the melody was too high or too low for you to sing? There are many things that can affect the way we project our voices when trying to hit a certain note or make a certain sound, such as what we drink. Before a performance most celebrities are known to drink room temperature water before their performance to help the dryness of their voice box. Can other liquids such as soda, milk or juice also affect the way we project …show more content…
This causes the volume in the lungs and chest cavity to decrease. So now the pressure inside the lungs increases. The air moves out because the pressure inside the lungs is higher than the outside atmosphere (Elaine Nicpon, 5/11/16). Along with our voice box we have this thing called the glottis, also known as the rima glottides; which is the opening between the two vocal folds. This opens during breathing and closes during swallowing and sound production, along with additional functions for singing. When the focal folds adduct, the glottis closes; when the vocal folds adduct, the glottis opens (Deirdre Michael, …show more content…
As you can see less air is moving through the vocal folds. On the right sight of the diagram, it shows the glottic cycle for someone who has a loud voice. More air is moving through the vocal folds than someone who has a soft voice. The glottis cycle is divided into phases: opening phase, open phase, closing phase, and closed phase. During the closed phase, the air pressure builds up below the vocal folds. When the glottis opens, the air explodes though the vocal folds, and that is the beginning of the first sound wave. To determine the loudness of the sound, it depends on the strength that you push through the larynx (Deirdre Michael,
