Karen Pence, "Last Saturday, we participated in a childrens music therapy group session at Childrens Medical Center Dallas. What a treat! We used instruments to express feelings of anger, mischief and happiness. We also used a song to introduce ourselves, and we finished the session writing our own lyrics to a song."
