I wish I could just enjoy her.
I’m a fan of good singing.
Where you enjoy Jackie’s voice, I hear a young girl with some natural talent forcing and darkening her young voice to sound unnaturally older. That trick is very dangerous to her young voice.
She needs to find a good voice teacher and fast before she develops some worse habits.
Beverly Sills was classically trained by Estelle Liebling, a former soprano and voice teacher who was the last student of Mathilde Marchesi. While Sills started voice lessons at a young age, Liebling never forced Sills voice beyond its years. Instead, Sills spent years just learning how to sing properly by mastering vocalises.
When the Sills voice matured with age, the technique was solidly in place.
If young Jackie wants to go down the opera road, she needs to be taught to sing correctly and to learn a correct technique, otherwise she will ruin her voice for opera.
She would be better suited to a pop route, but she still needs to learn to sing correctly and have some formal training. I wish her the best.
I’ll get off my soap box now.
