— -- Music has always been an important part of Christopher Duffley's life.
“Music to me is for one thing: it brings joy to people. Singing is a gift that I share. Because I'm blind, I see people with my heart for who they truly are instead of what they look like on the outside," the 15-year-old told ABC News.
Christopher, who had been placed in foster care as a baby, was raised by his aunt Christine Duffley and her husband Steve. The couple formally adopted him in 2003. "I wanted to do the right thing," Christine said.
"I wasn't looking to be a super mom,” the mother of four said. “A lot of families with special needs can identify with the day-by-day survival. I didn't know how to take care of a blind and autistic child. My kids loved Christopher and we want Christopher to be independent. We want him to thrive so we gave him as many things as we could."
Christopher learned how to communicate with others through his love of music.
“It was the music therapy where we realized that he really had talent, that he had perfect pitch, that the harmonies we heard were definitely a gift that he had,” Christine said.
His burgeoning singing career took off after he posted a now-famous video clip of the song “Open the Eyes of My Heart” in 2011 on YouTube.
“There wasn't a dry eye in the place and the ovation was crazy. It was just a beautiful experience because the choir was behind him,” Steve Duffley told ABC News. That video has been translated into multiple languages and viewed millions of times.
“I like singing because when I'm at an event, I know that it brings joy to people,” Christopher explained.
Christopher hosts a weekly “Mission Possible” podcast as a way to connect with fans and to encourage others living with disabilities to dream big. He even edits and engineers each podcast.
Christopher's music coach, Michael Shaughnessy, says the young man is a natural leader.
“He wants to advocate for people. He wants to move other people to action. I see that in him. That's a leadership quality I think he has,” he said.
Christine says Christopher is also teaching his peers about his disability and how he is very much like them in other ways.
"The kids get to learn things about blindness so that when they meet a blind person they're more comfortable. They realize ... that Christopher has the same dreams and aspirations. He's no different, he just does things differently,” Christine said.
