Deaf 'Dancing With The Stars' contestant won't be able to hear music

Video includes clips from ABC, The CW and Perez Hilton and images from Instagram.

He'll be the first fully deaf male contestant on "Dancing With The Stars."

"I haven't danced at all growing up. So, we'll see what happens," DiMarco signed.

"How do you choreograph when he can't hear the music?" ABC's George Stephanopoulos asked.

"Honestly, it's more visual. It's more of a challenge for me this season, but it's a great one," Peta Murgatroyd, DiMarco's dance partner, answered.

But DiMarco is no stranger to challenges.

"(I'm) becoming the spokesperson for the deaf community, and they need me. It's a burden sometimes, but I'm willing to take that burden and change the world's perspective on deaf people," DiMarco signed.
