Many people believe that singing is a Natural talent that God gave to us. But for me, by learning different tips to sing better is a one good way to improve singing voice.
What is not natural is the natural way of loosing weight, natural diuretics can work but not all of them, so be picky.
Regular practice is what will make a good singer. Having technical knowledge will not be enough on its own. There is no quick way to becoming a terrific singer. A lot of time and effort have to be invested regularly and your devotion can only rule over your singing chords over time. Never scream or shout while practicing as it affects the quality of your voice adversely. This has a very bad effect on the voice quality and your singing ability.
