It really depends on the effectiveness of your practice. At the end of the day, singing isn't just about playing the right notes. How long does it take to learn to sing? Exactly ten months and three days. If you think it sounds weird, you're right.
Some people are born with very little vocal ability, while others are naturally gifted singers. But everyone, from the shyest shower singers to the professionals, can always learn more about singing. Going from a basic level to an intermediate level of singing takes six months to a year of constant practice. As with other sports, constant repetition develops muscle memory.
Basketball players run drills at every practice. They run laps to gain endurance and practice all kinds of coordination exercises. That said, you can speed up this process by simply practicing more. The 3-year rule for me is a singer who practices 1 hour a day at least 5 days a week.
If you practice two hours a day, you can speed up this process tremendously. It all depends on how much you want it and your willingness to spend time. Tuning and tuning problems can often take a few months to correct;. It will depend on how much work you do in it and if you have any previous experience, but you can definitely learn to sing in less than 6 months.
Then move on, as you can continue to improve and develop your vocal technique. Maybe you just want to learn a simple song and sing it well enough that you don't feel mortified in front of your friends at karaoke. If you're learning from a teacher, how quickly you progress also depends on how often you have classes. Let's talk about how long it takes to learn to sing and what we can do to make the process a little faster.
Just as some people learned to walk faster than others or learned to speak before, people progress differently with the voice. You can learn a lot through weekly singing classes, singing courses or YouTube videos, but you need to continually USE the methods and techniques to get your muscle memory into action. Therefore, a secondary goal could be to learn how to make a better transition from the voice from the chest to the first bridge, eliminating a problem. Knowing what you want to work on and what you want to achieve will make a big difference in how long it takes to learn to sing.
Singing with a one-on-one teacher is certainly not the only way to learn to sing, but it can speed things up a lot for someone to adjust your technique in real time. Becoming a professional singer isn't just a matter of learning to sing, or even starting to sing well. If you want to go beyond the basics and learn to distort the voice, extend the voice from the chest as much as possible, etc. But after a few weeks of learning the technique and practicing, you will begin to see a noticeable improvement in your voice.
