The source of the voice are thevocal chords which are a valve which vibrates and works to chop the airflowproduced by the lungs into shorter, more manageable pulses that form the soundsource for the larynx. The vocal chords open when inhaling and close whenswallowing and singing. Vocal sound is produced by the lungs creating anadequate amount of air flow and pressure to then vibrate the vocal chords (alsoknown as the vocal folds.
) This pressured air then fuels the voice and createssound. The vocal folds are what allow the singer to have a large amount ofcontrol and help them to pitch their note more accurately and more easily whensinging. When the previously condensed air passes through the vocal folds itcauses them to vibrate and this type of phonation is called voicing. · Thedriving force of the voice is the diaphragm, which is a sheet of muscleseparating the thorax from the abdomen. A professional singer knows how tomanipulate and use the diaphragm to improve the quality and length of the soundthey produce and to insure that they are singing safely so that they do notdamage the vocal chords.
Singers believe that it is extremely important to knowwhere your diaphragm is so that you go on to strengthen it for singing. Singerswork to make them firm and stable, to give them a foundation for their voice torise through their air column. It is extremely important that singers make surethat the diaphragm muscles remain firm when they are breathing but not clenchedwhen singing, they also need to make sure that their chest, shoulder, and facemuscles remain loose to ensure that they are singing safely, using the correct muscles.To strengthen the diaphragm singers to various exercises such as breathingwithout moving the shoulders and then panting whilst keeping them still. Toensure that you are singing safely using your diaphragm a singer needs to focuson their posture because the diaphragm is below the rib cage which encloses thelungs, therefore sloughing pushes the ribs into the lungs so the singer cannotget enough air and sing as well a they could’ve with a straight posture.
Important ligaments needed to sing · The larynx (voice box) The larynx islocated in the anterior part of the neck in the level of the C3-C6 vertebraeand connects the pharynx with the trachea. The larynxis made of cartilage, muscles,ligaments and mucous membrane, guarding theentrance to the trachea, bronchi, and lungs and cages the vocal cords. · The Vocal folds (vocal chords) The vocal chords are stretchedacross the larynx from the front to the back.
The vocal fold are made of twininfoldings of mucous membrane. The voca chords are extremely important in orderto produce vocal sound and without them the sound would be impossible. · Soft palette Thesoft palette is located towards the back of the throat behind the hard palettein the upper respiratory system. The soft palette is made of muscle andconnective tissue making it very flexible and important when singing in headvoice and hitting higher notes.The ligaments which have a large impact on the toneand pitch of the voice. Pitch is controlled by the length and tensionof the vocal folds, controlled by the muscles in the larynx. Thevocal folds vibrate from 100 to 1000 times per second which is depending on howhigh pitch we sing. The diaphragm is extremely important when creating volume inthe voice, When breathing in, the diaphragm contracts, and pulls downwards toincrease the volume of the chest and air is sucked into thelungs meaning that a singer can control their volume using the diaphragm.
Your vocal folds arewhat make the sound, but a singers tone can be altered bymanipulating the different structures of their vocal tract. When the thyroidcartilage tilts forward slightly , the vocal cords stretch and are , thinnermore tension is built , affecting both tone and pitch. This tension usuallymakes a sweeter toned sound. Female vocal chordsare whiter than mens and the size in the vocal chords differ which is whataffects the pitches and makes men have a deeper voice however this rule is notalways correct as each person’s voice is different and has a slight difference in pitch.
Everything which is inhaledpasses straight across the vocal cords. Vocal cords react badly to irritantssuch as the smoke created via smoking. The burning end of a cigarette is 451degrees which is too hot for the vocal cords to handle. When the hot air getsabout 17-20 cm down the throat it can burn the vocal cords. And the tar andother irritants the cigarette causes can create swelling and can heavily damagethe cords. Repeated, long-term smoking of course causes tissue changes in thevoice which can permanently damage a vocalists tone. Shoutingis another way people can severely damage their vocal chords.
Repeatedly,screaming or just straining to be heard on a day to day basis can cause long term damage and frequently developswellings or nodules in the vocal chors which can stop someone from being ableto sing.
