Amergin, don´t be good at following NEGATIVE directions :)
This process (training voice) is very slow and needs an experienced teacher. One thing that most people are scared about when deciding to go to a teacher, is being converted into an opera singer. It´s a myth. Even when you realize, after some classes, that you are producing a sound that resembles a classical voice, that´s not bad at all, it signals a progress. Further on you decide how you will sound.
Ella, that´s good ! Although the classical music loses many good voices for a lot of reasons, it´s good that other genres benefit with them. I´m sure your audience will appreciate the quality.
Un abrazo - Andrés
