One common cause of a hoarse voice, that a vocalists gets after letting out their voice suddenly, loudly, and emotionally is unbalanced muscles relating directly to vocalization production.
The vocal cord is moved by other muscles, not by itself.
If these muscles lose balance, air will leak out while breathing. This air needs to be kept steady to hold a smooth consistant vocal sound.
If you can first understand which muscles are used to move the vocal fold, then you can find solution and keep control, which will correct the hoarse voice.
Note：The following figure shows an example of when the vocal cord misbalances and makes a hoarse voice. When one side of the vocal cord muscles is strained, the vocal mucosa either becomes dry or the mucosa of the vocal cords thickens.
Only stretching the neck does not directly effect vocalization, because muscles move the neck. Those neck muscles do not connect to the muscles that are used for vocalizing.
If these muscles connected to each other, your tone would change when you moved your neck, which does not happen.
The larynx is suspended by the stylopharyngeus muscle and the stylohyoid muscle in the air.
The larynx moves freely in the air, and makes the resonance chamber in the front of the cervical spine able to produce good sound.
You actually need to stretch to move the larynx well.
If you extend or massage the muscles around the larynx, these actions can directly impact your voice. Noticeably in time, your vocalization will definitely improve.
Although, only stretching of the neck itself does not relate to vocalization.
Luciano Pavarotti used to cancel his concerts often, due to not having a good vocal condition at that time, and Salvatore Licitra is famous for being his substitution.
The even a world-class opera singer can suddenly fall into a slump, and not be able to sing a song.
No wonder, you have a slump sometimes for singing. That’s why! It is common and happens to even the best.
Vocalization is operated by the vocal cord, breathing, the musculus extrinsic laryngis and vocal mucosa. The thickness of the vocal cords’ mucosa can be changed by the humidity and this change directly affects the voice.
Furthermore, the condition of the musculus extrinsic laryngis can also change suddenly by just a mild cough or sneezing, as well as your breathing being changed by the body’s positioning/stance.
The voice is significantly affected by such small matters.
The following 5 factors are suggested for preventing your voice from entering a state of bad condition:1.Improve the blood circulation of superior laryngeal artery 2.Improve the flexibility of the musculus extrinsic laryngis 3.Improve muscles of musculus extrinsic laryngis 4.Improve breathing techniques for your singing 5.Keep a strong mental balance

Note:Professional singers have to impress people in order to make them want to listen to their singing. If you feel that today is impossible to make an impression on listener due to a poor state or condition, then cancelling the concert is probably a smart choice. However, keep in mind the audience is going to be disappointed with any cancellation of event. That’s exactly why you have to take good care of your throat all the time.
