Hi, If anyone could answer that would be great!

I am about to do the Estabrooks course but I'm am slightly weary it may not be the best for me. I am aware he has a more opera style, whereas I tend to sing with less vibrato in a more smooth pop style. Will this course still help me with my specific voice or is it specific to his style?

Good question, Joe! Even though Estabrooks is classically trained, his course isn't specific to classical singing. You can check out my and Jon Statham's course, though, and see if one of us is a better fit!

Thanks much appreciated!

Sure thing!
