Things to Do to Improve the Singing Voice
It is good to note that as a singer the first thing is to believe in yourself because no one will do that on behalf of the person and the singer has to be confident if they expect to sing in the best kind of voice. A fact worth stating is that a confident singing voice has a ringing, vibrant, and well-projected tone but if the person lacks confidence and they are worried on how they sound they can begin a program of positive confirmations and visualizations to connect the person with their inner power. The individual can create anything they need, want, then affirm their creation by repeating it repeatedly and then visualizing themselves singing in a place full of people, and then listen to the beauty and richness of their singing tone that is very confident, grateful, and eager to share the message in the song.
A known fact is that the singer has to open their mouth to sing with a powerful and confident voice because when the mouth is barely open the musical tone will be suppressed, or hidden-sounding and the person needs to create adequate space for the sound to come out. It is worth stating that the person needs to be self-conscious about a generous mouthwatering, and the tone will only ring if the person opens their mouth wide enough for the sound to ring. It is irrefutably true to state that the singing has to be given a boost by keeping the mouth open as the person sings because this leads to a more potent song and to make sure that the mouth is open wide enough the singer can place two fingers between the bottom and top of the teeth. The singer has to keep the fingers in the mouth singing ‘ah’ then remove the two digits from the mouth while retaining the ‘ah’ sound.
Diaphragmatic or belly breathing is integral for a better sounding singing voice and the tone that one sings in rides on the air that is being exhaled as the person sings. When the singer commences phonation (singing or speaking), air makes vibrations to occur which produces sound and will continue to do so until the person runs out of air. The person has to remember that if they are currently breathing in the air by the use of the upper section of the lungs, they will run out of hair very soon and have a breathy and weak sound. Learning how to inhale by inflating around the waistline takes lots of practice and the more the person repeats the belly breathing exercises they will unlearn the wrong way to breathe and learning new ways to breathe.
