Canta is a software designed to help you to learn to sing in tune.
Singing in tune is mostly a matter of ear. Many people do not realize that they sing false because their ear is not sufficiently trained to recognize the sounds of the same height. And others are aware that they sing false, but they do not know how to correct their voices.
Canta is there to show you graphically, if you sing in tune or not, and in what direction it is necessary to make corrections. You can see if you are too low or too high and how much. Then you can correct your voice. Through a regular and repeated training, your ear will eventually learn to make corrections itself, and you can finally have the pleasure of singing in tune.
The Canta help is presented in several forms to allow you to have greater access to the information you need.
