Don’t be fooled by teachers promising the world!! I believe in encouragement but I also believe in honesty with all of my students.
When teachers tell you that you can sing like “Nickelback” or have as much sound as “Jennifer Hudson”, run the other direction.
Some singers are born with massive instruments and cords of steel. We try to mimic them and end up with a multitude of problems. Don’t fall for promises you know deep down are not true. Learn to appreciate the voice you have and develop that voice to it’s full potential.
