I’ve said before that I’m not a big fan of classical voice training for commercial singing. I’m happy that I never had voice lessons when I was a teen.
The reason being is that I learned what my voice can and can’t do on my own…long before I ever took a voice lesson. Classical training would have suggested my coordinations for resonating with a high tongue and slightly high larynx were incorrect. Teachers would have opened up the back of my throat, thus creating a “classical” sound. Years of this type of training would have squashed all my instincts that have taught me how to belt and sing freely in my high range with a commercial sound.
However, teens now have options. Classical training is not the only road to good technique.
