Watch and observe, children. They PLAY their instruments and sing with competence. They know their instruments and have spent a lot of time practicing and learning their skill. No Autotune. No computerization doing it for them. This is something called talent. Talent was a skill from decades ago before Autotune, before computerization, before the record industry picked young people to become stars based on visual appeal and how far a person would go with publicity stunts to create shock value. These talented musicians of the past had creativity, commitment, flair, skill, and put in a lot of time writing and polishing their songs. Many of them read what is called sheet music. Sheet music is a kind of language for music using what is called notes. Sheet music and notes kind of equate to learning how to write language and use what is called grammar. Grammar are the rules and guidelines of language. Music has a grammar to it, as well. In both writing language and music, creativity may be used to create magnificent songs, such as the one on this video. However, you will have to learn what is called discipline. Discipline requires something called work. Discipline and work will give you the means to learn how to actually sing and play instruments on your own without computerized assistance. Once you become good with singing and playing instruments, something called your self-esteem will improve. You will develop a sense of what is called accomplishment, like these young lads in the video.
