One of the problems with being 'taught' to sing is the tendency towards imitation.[quote ]
fair point, [as regards style]which is why it is better to expose people who wish to improve to as many good singers as possible, and let them develop themselves.
but good breathing technique can be taught,as can the art of performance,extending vocal range, warm up exercises [etc].
suggestions can be made about repertoire.
however many people imitate without being taught, case in point isSuibhne O P, who is noticeably influenced by Peter Bellamy,I can think of another singer who hasa noticeably influenced style,neither were taught by P Bellamy
