“In praise of children’s singing abilities”

Children are able to make sensible judgements, which lead them to unerringly reveal any stiffness or artificiality in a bad singer. If they have the chance to listen to good role models, this ability is trained and intensified. In the opposite case they lose this ability and - just like most adults with the same "handicap" - their opinions as listeners are later easily swayed by critics, advertising campaigns and the public media.
Another wrong opinion is that young children are incapable of properly learning anything about singing. My own experience is that one can systematically work with children using games starting from the age of three, when one must make sure that they do not adopt incorrect breathing and singing habits. It is beneficial to sing to them, and gradually with them, from the very beginning. From about five years of age they can be gently taught basic singing technique skills.
Between the of age six and seven (depending on a child's mental and physical maturity), a child is entirely capable of consciously perceiving and imitating singing sensations. In this period we may begin systematic instruction, including teaching the singing form and the sensory connection between the resonance form and the diaphragm.
This fact negates another myth: that children are not capable of singing supported on the diaphragm, or appoggio. Referring to my own experiences, I can say without hesitation: children are capable of appoggio and there is no reason why they should not be. Only the underestimation of children's abilities by uninformed teachers can lead to such an wrong opinion. Listening to an excellent child soloist YT1 or two of my current child pupils YT2 + YT3 should convince you of a child's ability to sing using appoggio.
