Adele is known for her unique vocals, but she's not the only one who can pull them off. Fellow musician "The Tonight Show Starring Jimmy Fallon" Tuesday night.

There to promote "The Voice" Season 12, the judge and host Jimmy Fallon each took turns with the musical impression generator, a tool that matches a random artist's name with a song title. The lyrics must then be performed in the style of the musician. While playing, Keys had to make herself sound like Gwen Stefani and Janis Joplin, but it was her impression of the Grammy-winning Brit singing the alphabet that stole the show.

Watch Keys do her best Adele impression below. We'd turn our chairs for her in a heartbeat.

"The Tonight Show" airs weeknights at 11:35 p.m. ET/PT on NBC.
