Transcript of Vocal Cords
By: Anna Martinsky
How do they work?
Closed when holding breaths, open for inhalation and vibrate when you speak or sing
Air is taken in when the vocal cords are open, and close when exhaling
When speaking or singing, air is pushed against the vocal cords, causing them to vibrate
What are the vocal folds?
Nodules- Vocal nodules or "nodes" are noncancerous bumps that appear on the vocal cords
1964 Academy Award winner for the title role in Disney's Mary Poppins

Two infoldings of mucous membrane
They are inside of the larynx and at the top of the trachea
Used to make sound and produce speech and singing
Male: 17-25 mm in length
Female: 12.5-17.5 mm in legnth
When singing, the vocal cords thicken or lengthen to create lower or higher pitches due to the changing tension in the TA muscles
For lower pitches, the TA muscles have less tension, causing the vocal cords to be thicker and shorter and make lower pitches
For higher pitches, the CT (Cricothyroid) muscles are used to lengthen and thin the vocal cords as the pitch is raised
Singing requires breath support from the diaphragm to keep notes on pitch and not fall flat or sharp.
Singers are often told to stay away from certain foods and drinks before singing such as dairy, because phlegm will build up around the vocal cords, making it harder to sing pitches correctly
Warming up is also an essential part of singing to ensure that the vocal cords are healthy and able to sing well
Strain- Vocal strain occurs from using the muscles around the vocal cords too much when singing or speaking
Laryngitis- Laryngitis is the result of inflammation of the vocal cords, making it difficult to speak or sing
Strain can also be caused by over using the vocal cords and putting too much pressure on them when singing
Symptoms of include hoarseness, a "lump in throat feeling", pain from ear to ear, voice and body fatigue and decreased range
Can be caused by oversinging, excessive belting, and/or excessive use of riffs or runs
Surgery is an option to get rid of the nodes and is commonly used, but complete vocal rest is also an option
Was diagnosed with a vocal problem in 1997 and opted to undergo surgery to fix the problem
When she came out of the surgery, she could barely speak
She is now speaks with a slightly raspy voice and can barely sing. Andrews does what she calls "speak singing" and can hit a few base notes
Before the surgery
After the surgery
