There is only one way: study. Because you must know that there are many people who can sing, and just being able to sing is not enough. You must study systematically. What's more, you are only 17 years old. If you are still in school, you can first learn Primary 3 - music. Then, apply for this kind of music-related university, but if you want to be sure, you can also learn some musical instruments for the exam. But as long as you are admitted to this kind of school, you can study systematically. So, I feel that if you start singing now, it’s too early and you won’t achieve much development. Moreover, you are not too old, so you should be very promising. However, if you don’t go to school now, you can also sign up for that kind of music class and take the exam. If you don’t want to take the exam, you can also study systematically at that time and then learn to play an instrument, but this should be better than the first This is more difficult to implement (referring to the future). However, you can also put your own songs on the Internet like some people who like music now, which is not bad. Of course, if you can arrange music, but don’t know how to make music, or don’t want to learn. You can also buy that kind of software, and with that kind of software you can create on your computer. Come on! Hope it helps.
