DD will be 8 this month. Yes, a great deal of care must be taken when training the voice and I trust this teacher very much. DD is singing age and range appropriate songs while learning theory, breath technique, and stage presence. Her piano teacher was teaching her singing and had to stop after 2 years because she had reached the end of what she could safely teach her. This is how we ended up with the audition for the new teacher.
Singing meets a deep need inside of her that we can't place a price tag on.
I wonder if this is a new thing we can cite to show parents that really gifted isn't "better." It's not better, it's just more expensive. LOL!
