Other forms: crooners
A crooner is a singer, especially a man who sings jazz standards. Frank Sinatra was a well-known crooner.
The noun crooner describes a silky-voiced singer of sentimental jazz favorites, particularly a male singer. Crooners were especially popular from the late 1920s until the early 1950s. The increased use of microphones and radio broadcasting made it possible for crooners to sing softly and emotionally even when backed by a band. The rise of rock n roll helped bring the era of the crooner to an end. Crooner comes from the verb croon, "to sing softly and sadly."
