A lot of factors are at play in order to produce or create a good singing voice.
While some of these factors are certainly what someone would call God-given gifts (the structure of one's nose, mouth, tongue, among other things), a few more can actually be worked on and improved.
You should focus on training that can improve controllable factors like your breathing, your lung capacity, your ear for pitch and your voice range.
You may have heard of training for several of these factors, but most people are unaware that you can actually train your voice to increase its range.
Most singers and vocal coaches never challenge the belief that vocal range is purely because of sheer natural talent, but this isn't so.
What most people take for granted is the fact that the vocal chords is like any other instrument.
You have to take care of it, you have to maintain it.
One of the common ways people unwittingly do to hurt their voices is the constant intake of alcohol and caffeine.
These substances are very drying to the throat and thus it is best to avoid them.
Lubrication is important to your voice and you can ensure this by keeping yourself hydrated and drinking at least 6 to 8 glasses of water a day.
Rest as well as exercise are equally vital to your voice's health.
If for instance you wake up with a raspy or sore throat, it is best if you avoid using your voice and speaking especially if it hurts when you speak.
Give your voice the time it needs to recover or rest.
If the throat problem doesn't go away in 3 or more days, it would be a good idea to call the doctor.
Exercise on the other hand is a great way to promote good posture and proper breathing,which are both important components that lead to a good singing voice.
Increasing lung capacity gives your voice power.
One method you can do to achieve this is controlled breathing.
Breathe in and exhale slowly.
Then for your next succeeding inhales, make sure you take in air in half the time it took in your previous try.
Exhale slowly.
Sustain longer breathe-outs as your inhale time decreases, this is the main idea.
When you have a larger lung capacity, you also prep your system up for a wider vocal range.
A more direct way of increasing your range is through an exercise called tongue trills.
These are just a few tips you can do to care for you voice, but for more tips you should consider enrolling in singing program.
Online singing programs are less expensive than a singing tutor.
There are several available on the market, but not all of them are worth your time or money.
Do some research to find a well respected program that will work for you.
