There are those who believe that it is impossible to hear oneself objectively, and therefore advise the student to “sing by feel,” which is a bit like driving an automobile without looking at the road. While it is quite true the performer does not hear objectively, the fact remains that to sing without a tonal concept is not only impossible, but undesirable. Learning to improve one’s vocal skill depends on a sharpening of tonal concepts and tonal concepts are developed through the development of listening skills.
