What is a crooner? Crooning is a sentimental, often emotional singing style. This once dominant popular style coincided with the advent of radio, and electrical recording. Before the microphone, singers like Al Jolson had to project to the rear seats of a theater which made for very loud singing indeed. After 1954 popular music became dominated by other styles, especially rock 'n' roll, while the music of latter-day crooners such as Perry Como and Matt Monro was recategorized as easy listening or adult contemporary. Crooners have remained popular among fans of traditional pop music, with contemporary performers such as Tony Bennett, Barry Manilow, Michael Stipe, Morrissey, Harry Connick, Jr., Michael Bublé and Neil Hannon keeping the form alive.
