Some of the biggest singers in the world that use minimal technique have naturally good voices. What do you tell people that sound horrible, “Just sound like so and so”? People that just don’t have it need techniques and practice. Many teachers are stuck in one method which may work for some and not as well for others. Too many teachers saying, this is what I do with all of my students. A great vocal coach has a deep all around understanding and can apply specific technique individually not just developed a cookie cutter method.
