HOW LONG DOES IT TAKE TO BECOME
A GOOD SINGER?
You know for sure this is an individual thing. BUT I can tell you this: whatever class you're attending, RUN AWAY if you have not seen ANY improvements for months.
Whether you're more or less talented, it's not your fault if you don't find any kind of benefit out of your lessons. Think about this: what happens when a football team don't perform well? First, their coach get dismissed.
This has got nothing to do with the professionality of the coach. I´m not saying the coach is not good. But what I'm suggesting here is that the pair team-coach could be not a good fit.
If you're in this situation, the best choice is to run away, before losing your enthusiasm. Just give yourself another chance and consider to try a different approach.
A few lessons will be enough to find the first benefits, but you’ll need to practice, just like you would do in learning any other instrument.
Please believe that shortcuts and magic words don’t exist, but do believe in yourself and take the time for your passion!
