One thing that has been a defeat to classical singers and teachers, and still persists as an issue, is the comprehension of musical and sound requires by voices used for contemporary purposes and the reject of some sounds in the voice. We (classical singers and techers category) have not made properly, in the past 40 years, the path toward the appreciation, the recognition and the knowledge about pop, rap, jazz, rock and extensively contemporary voices and so depriving of the appropriates and correct tools coming from our technique for this different kind of use of voice instrument. I still hear judgements on the quality of sounds in classical terms to judge and comprehend those voices. Please make a step forward  and understand that many things can be done even with not round and classically sustained sounds, as my work and many singers show. They need our tools, modified and readjusted for their sound and we need to be and to shape and use the knowledge we have for musical needs and not ideal singers of always the same repertoire.
