Carol Kaye (

born March 24, 1935) is an American musician. She is one of the most prolific recorded bass guitarists in rock and pop music, playing on an estimated 10,000 recordings in a career spanning over 65 years.

Kaye began playing guitar in her early teens and after some time as a guitar teacher, began to perform regularly on the Los Angeles jazz and big band circuit. She started session work in 1957, and through a connection at Gold Star Studios began working for producers Phil Spector and Brian Wilson. After a bassist failed to turn up to a session in 1963, she switched to that instrument, quickly making a name for herself as one of the most in-demand session players of the 1960s, playing on numerous hits. She moved into playing on film soundtracks in the late 1960s, particularly for Quincy Jones and Lalo Schifrin, and began to release a series of tutoring books such as How To Play The Electric Bass. Kaye became less active towards the end of the 1970s, but has continued her career and attracted praise from other musicians.

During the peak of her years of session work, Kaye became part of a stable of Los Angeles–based musicians known as The Wrecking Crew. She appeared in the 2008 documentary The Wrecking Crew. Kaye was the sole regular female member of the Wrecking Crew (though she has said the collective were never known by this name, which was later invented by Hal Blaine), a collective of studio musicians who played on a large number of hit records from Los Angeles in the 1960s. Throughout the decade, while at the time unknown to the public, Kaye played bass on a substantial number of records that appeared on the Billboard Hot 100. According to the New York Times, she played on 10,000 recording sessions. She appeared on sessions by Frank Sinatra, Simon & Garfunkel, Stevie Wonder, Barbra Streisand, The Supremes, The Temptations, the Four Tops and The Monkees. She played electric bass on Nancy Sinatra‘s “These Boots Are Made for Walkin’“, while Chuck Berghofer played double bass. She also came up with the introduction on fellow session player Glen Campbell’s hit “Wichita Lineman“. Kaye later said that during the 1960s, she would sometimes play three or four sessions per day, and was pleased that so many of them created hit records.
