While the benefits for beginners and others are enormous, make no mistake, the voice lessons are for both professional singers and aspiring singers. Singing lessons are the perfect way to reach your full potential. I think that informal teaching and training absolutely count, and it's a big part of the influence of so-called untrained singers. It's definitely not about having decades of private classes and a master's degree (although that's a path), but just learning and exposing yourself.
Behind almost all the great singers there is a vocal coach. Voice classes are essential for aspirants and even well-known singers. Any singer who wants to make their singing career really needs to work on practicing and singing as much as possible — there are TONS of singers trying to score big, and you have to find ways to stand out. Singing lessons are worthwhile because they give you the opportunity to improve your voice through training and practice.
Singing correctly means being able to sing throughout the range without any tension, sudden interruptions or sound inconsistencies. Some artists are also guilty of common vocal failures, such as tongue tension, throat tension, nasal singing, tone or detuning. Another is that singers will want to make sure they can continue singing without damaging their vocal cords from overuse or improper technique. Singing classes give you the opportunity to test your skills, taking your voice beyond any perceived limits.
Finally, vocalists learn to become great rock singers when they learn to connect their feelings and emotions with their singing. You hear a lot that there is no substitute for classes, but I find it hard to believe that all these very different musicians from different walks of life have taken singing lessons. That means that the only singers who qualify not to have classes are singers who were naturally talented, but somehow decided not to take music classes in high school and not sing in choirs and not do concerts. As you take singing lessons, you'll find out exactly what that range is, as well as which songs fit your comfortable range best.
If you're having trouble distinguishing notes or getting your voice to the right pitch, this doesn't mean you have to give up hope of ever singing well. There are also rock singers whose techniques have a lot of room for improvement due to nasal sounds, screams, weak vocal cords and tongue tension. They try to sing like Adele (surgery for polyps and vocal hemorrhage 201), or Sam Smith (surgery for vocal hemorrhage 201) or like Freddie Mercury (he had vocal ganglia but refused surgery). They admitted that, when they started with Anderson after singing for years, their lessons changed their careers and even helped them win an octave.
Once an artist starts doing big tours, it would be normal for a vocal coach to be there if people on the label thought there was any chance of damage.
