Listen to more and more songs, and then try to sing them. Listen to your voice when you sing, and it’s better if you sing alone and in a private place. Be determined to sing properly. if you want, you may record your song. Listen to it later on, and compare it with the original. Identify your flaws and work on them. When you feel confident, ask your friends and family to listen to you singing (but don’t go for super-flatterers). Don’t ignore their suggestions and criticisms. When you are more sure of yourself, participate in singing competitions. The advice of the judges, along with the singing of fellow participants will help you.
