Chris Martin's key piece of advice for "The Voice" contestants: Get moves like Mick Jagger.

The Coldplay frontman will be joining "The Voice" as the official mentor for second phase of the Battle rounds, which begin Monday -- and by the looks of it, he's wasting no time voicing his opinion.

In the first clip released from Martin's appearance, he is seen visiting coach Blake Shelton and his contestants, Audra McLaughlin and Megan Ruger, who were in need of some stage-presence tips as they practiced their performance of Miley Cyrus' "The Climb."

"This is a song about trying to get somewhere together, so cover the area," Martin advises. "You need to bring out your Mick Jagger's a bit; he goes everywhere. You feel as an audience, 'Oh, he's coming over to me.' That's why he's the best frontman in the world."

The upcoming guest spot, which marks the typically camera-shy rocker's American reality-show debut, is the first of three episodes Martin will appear on (March 31, April 1 and April 7). In addition to Shelton, he will work with the other coaches -- Usher, Shakira and Adam Levine -- and join season-six mentors The Band Perry, Aloe Blacc, Jill Scott and Miranda Lambert.

Martin isn't the only shakeup coming to "The Voice" in the next few weeks. For the first time, contestants will be performing a sudden-death sing-off, which will be replacing the old knock-out rounds and has contestants pair off to perform the same song separately.

Martin, whose band is releasing its sixth album, Ghost Stories, on May 19, recently announced his split, or "conscious uncoupling," with his wife of over 10 years, Gwyneth Paltrow.
