The 36-year-old star, who made a New Year's resolution to 'learn new things', is now on the hunt for a professional tutor for the instrument.
"I'm going to shame myself into getting better by showing you, where I'm at. Two and a half weeks into learning how to play the piano. Bare with me, this is going to be brutal," Tatum said in a clip posted on social media. "Hahaha! Keeping my New Year's resolution to "learn new things". But teaching myself piano is brutal. Got to get some legit lessons soon."
