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. For most people, it usually takes three years to tear down all the foundations. That said, when you have all the fundamentals as a singer, you'll be a very good singer.
The voice is one of those instruments in which simply laying the foundations is such a task that most people never get to that point. If you are looking to go beyond the basics and learn to distort the voice, extend the voice from your chest as much as possible, etc. It may take another 2 years of diligent practice to lower that. How long does it take to learn to sing? Well, it really depends on the level and type of music you want to sing.
It is a process of skill creation that lasts a lifetime. You never stop learning, but the basics can be learned very quickly. Tuning and tuning problems can often take a few months to correct;. But I usually advise people that it could take 6 months or more to notice a clear difference.
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. 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. But after a few weeks of learning the technique and practicing, you'll start to see a noticeable improvement in your voice. Whether it's to pass that big test, qualify for that big climb, or even master that cooking technique, people who rely on mannequins rely on them to learn the critical skills and relevant information needed to succeed.
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. You may have noticed right now that there is no set time to learn to sing, and that's fine. 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. If you're learning from a teacher, how quickly you progress also depends on how often you have classes. 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.
