Learned skill
Singing accurately is not so much a talent as a learned skill that can decline over time if not used. (…) No one expects a beginner on violin to sound good right away, it takes practice, but everyone is supposed to be able to sing. (…) Being called 'tone deaf' can have devastating effects on a child’s self-image. (…) People need a place to sing and have fun without worrying about how good they are.
