However, your goals must be realistic and achievable. Voice lessons will improve the sound you already have, but they won't guarantee you a singing voice worthy of fame. Everyone can learn to sing better, and a voice teacher can help you learn how to use your voice to the best of their ability. If the goal is to access your full potential as singers with an emphasis on an easy, natural sounding tone, you're in the right direction.
The answer to this depends on how predisposed you are to sing through your natural experiences and abilities. Almost anyone can learn to sing basic tuned songs, but actually singing, at the highest level your potential allows, is going to take a lot of hard work. Research carried out by several universities has shown that training and practice are more a factor than the natural ability to learn to sing. This means that, wherever you are on the talent spectrum, raising your level will require hard work, and by definition, hard work is hard.
Of course, this doesn't mean you shouldn't go ahead. It is a great satisfaction to work towards and achieve a difficult goal. Start with the basics and then gradually move towards more challenging goals with your singing. People with this condition are unable to discern differences in tone.
Since it is so rare (about one person in 70), the vast majority of people can improve their ability to match the tone with the guidance of a good teacher and with enough practice. If you decide to do so, adopt the beginner's mentality. That is difficult for certain personality types and has nothing to do with age. Someone may be 70 years old and have a wonderful acceptance of the fact that they are starting something new.
You have to show everyone how unique you are, not a karaoke version of someone. That is very important and what I try to work on with all my students. Most of my students are between 10 and 17 years old and that's what I really love to do. Learning basic theory means understanding, analyzing and being able to recognize various forms of music, such as major and minor scales, basic triads (3-note chords), seventh chords, tensions, modes, and also rhythmic patterns and constructions.
You can take a class, read a music theory book, or watch some great videos online to learn music theory. Your voice is essentially a musical instrument. If we can improve the way we sound when we use any other musical instrument, why do we think we can't improve our voice? People come in different sizes and shapes, so the “best way to sing for anyone is the way that leads to the best (or most pleasant) result, without causing damage to the vocal cords (more on vocal health later). If you get a vocal coach (a good one), he will teach you the proper technique for singing, as well as warm ups to help develop your voice.
