If you don't have cable, you can still watch "The Voice" Season 21 online. The singing show marks the first time pop star Ariana Grande joins the coaches' lineup. She will serve as a judge along with Blake Shelton, John Legend, and Kelly Clarkson. Carson Daly will serve as emcee.

Additionally, live viewers will return for the first time since the start of the pandemic.

As always, Season 21 of The Voice will begin with blind auditions. The coaches listen to the hopefuls sing, and if they want them on their team, they push a button to turn the big red chair around and see what happens.

After the blind auditions comes the battle round. This year's battle advisors are Jason Aldean for Team Kelly, Camila Cabello for Team Legend, Kristin Chenoweth for Team Ariana, and Dierks Bentley for Team Blake. In the finale, one singer will be crowned the winner of "The Voice" with a $100,000 cash prize and a record deal with Universal Music Group.
