Known for her distinctive, powerful voice, as well as her leading roles in musical theater, she has been called "the undisputed First Lady of the musical comedy stage."

She is also known for her film roles in Anything Goes (1936), Call Me Madam (1953), There's No Business Like Show Business (1954), and It's a Mad, Mad, Mad, Mad World (1963).

Merman introduced many Broadway standards, including "I Got Rhythm" from Girl Crazy, "Everything's Coming Up Roses", "Some People", and "Rose's Turn" from Gypsy, and the Cole Porter songs "It's De-Lovely" (from Red, Hot and Blue), "Friendship" (from Du Barry Was a Lady), and "I Get a Kick Out of You", "You're the Top", and "Anything Goes" (from Anything Goes). The Irving Berlin song "There's No Business Like Show Business", written for Annie Get Your Gun, became Merman's signature song.
