There are numerous tips or training that can be used to show you how to improve your singing voice, or how to improve the quality and clarity, which is also called diction, when you sing. There are also what amounts to some tricks to making your voice sound better if you have the right equipment. We are trying to learn how to improve your voice for singing in front of an audience the natural way.
That said, a very experienced vocal coach has something that is called, “the instant vocal fix”, it is a fast method that makes you sound better almost instantly.
For this you need yourself and a mirror. Watching yourself in the mirror, you need to say the English alphabet vowels, A-E-I-O-U, when you say them watch your jaw in the mirror. What you are watching for is that your jaw is not allowed to close while you are saying the vowels.
If your jaw does close then take your first two fingers and hold your jaw down at least 2 inches and repeat the exercise. Another recommendation by a different coach but talking about this very same exercise was to use a plastic bottle or a wine cork to prop your jaw open.
Both coaches said you need to stand in front of the mirror and repeat the vowel sequence at least 100 times, what you are trying to do is to reprogram your muscles memories and repetition is the secret to that reprogramming.
Once you’ve completed the exercise is time to move on to the second part of this method, this is how to improve your voice when you are singing. Using whatever methods you use before to keep your jaws apart you are now going to sing the vowels. You need to sing them in a single pitch, that means they are all the same sound. Here is another tip:
Again you need to repeat and repeat until your muscles can do it without any aid or props. Once you can do it, singing the vowels without closing your jaw you are ready to go on to the next step. The next step is to sing a line or a phrase from a song you know.
The objective is when you sing the vowels in the line your jaw should be in the correct position, like it was when you were singing the vowel sequence, it should take some practice but will be easily accomplished in the end. Both singing coaches say there is no set in concrete time or number of repeats it will take, different people take different times and numbers of repeats.
You should also notice a rapid improvement in the sound as you get the position of your jaw correct. The sound will be louder and more resonant with much less vocal strain required. This method is all about repetition so do not be afraid to repeat and repeat and repeat, if you persevere it will happen and you will learn how to improve your voice quickly.
