There is no doubt that intense involvement with tone evokes deep emotion. In a concert hall a single performer immersed in the simplest line can move hundreds of people to tears. Is it any wonder that a child's intense involvement with tone evokes emotion among family members?

The difference is that the emotion in the family context probably takes the form of greatly magnified familial tension that underlies every manifestation of individuality on the part of a single child, or parent for that matter.

When so much music training has emphasized pleasing the ear of others people often find it heretical to imagine music as something done for one's own pleasure.
