Alicia Keys , a coach on The Voice, proved Tuesday on The Tonight Show that she can be a student of voices as well.

In a game of random musical impressions with host Jimmy Fallon , Keys hit the right notes while impersonating Adele on The Alphabet Song. It isnt to the letter, but its good enough to wow the house.

Props for her Janis Joplin on Twinkle Twinkle Little Star, also.
