As part of Night of Too Many Stars: America Comes Together for Autism Programs, 11-year-old Jodi DiPiazza — who was diagnosed with autism at age 2 — took the stage, sitting at a huge grand piano, and played Katy Perry’s “Firework.” As a baby, Jodi did not speak or make eye contact. At three, she struggled with speaking, but began singing, constantly. With ABA therapy, it became clear that she had perfect pitch. Now she’s a serious music student.
