Vocalist Rosemary Clooney's rise to fame in the '50s came on the strength of songs that in many instances were without question novelty tunes; she's not a vocal improviser like Carmen McRae, Betty Carter, or Sarah Vaughan. She is an excellent lyric interpreter, has fine timing, phrases skillfully and intelligently, and performs with the dramatic quality evident among all great singers. Her background and foundation are jazz, even if her technique doesn't always adhere to rigid jazz scrutiny.
