The Nashville sound originated during the late 1950s as a sub-genre of American country music, replacing the chart dominance of honky tonk music which was most popular in the 1940s and 1950s. Although it refers to a means of production (not to mention an era and mystique) as much as to an actual sound, the Nashville sound is generally dated from 1957 or 1958.^{[unreliable source?]}

The Nashville sound was pioneered by staff at RCA Records and Columbia Records in Nashville, Tennessee, including manager Steve Sholes, record producers Chet Atkins, Owen Bradley, and Bob Ferguson, and recording engineer Bill Porter. They invented the form by replacing elements of the popular honky tonk style (fiddles, steel guitar, nasal lead vocals) with "smooth" elements from 1950s pop music (string sections, background vocals, crooning lead vocals), and using "slick" production, and pop music structures. The producers relied on a small group of studio musicians known as the Nashville A-Team, whose quick adaptability and creative input made them vital to the hit-making process. The Anita Kerr Quartet was the main vocal backing group in the early 1960s.
In 1960, Time magazine reported that Nashville had "nosed out Hollywood as the nation's second biggest (after New York) record-producing center."

James Travis "Jim" Reeves (August 20, 1923 – July 31, 1964) was an American country and popular music singer-songwriter. With records charting from the 1950s to the 1980s, he became well known as a practitioner of the Nashville sound (a mixture of older country-style music with elements of popular music). Known as Gentleman Jim, his songs continued to chart for years after his death. Reeves died at age 40 in the crash of a private airplane. He is a member of both the Country Music and Texas Country Music Halls of Fame.

Reeves was born in Galloway, Texas, a small rural community near Carthage. Winning an athletic scholarship to the University of Texas, he enrolled to study speech and drama, but quit after only six weeks to work in the shipyards in Houston. Soon he resumed baseball, playing in the semi-professional leagues before contracting with the St. Louis Cardinals "farm" team during 1944 as a right-handed pitcher. He played for the minor leagues for three years before severing his sciatic nerve while pitching, which ended his athletic career.^{[citation needed]}

Chester Burton Atkins (June 20, 1924 – June 30, 2001), known as Chet Atkins, was an American guitarist and record producer who, along with Owen Bradley, created the smoother country music style known as the Nashville sound, which expanded country's appeal to adult pop music fans as well.

Atkins's picking style, inspired by Merle Travis, Django Reinhardt, George Barnes and Les Paul, brought him admirers within and outside the country scene, both in the United States and internationally. Atkins produced records for The Browns, Porter Wagoner, Norma Jean, Dolly Parton, Dottie West, Perry Como, Elvis Presley, the Everly Brothers, Eddy Arnold, Don Gibson, Jim Reeves, Jerry Reed, Skeeter Davis, Waylon Jennings and many others.

Among many honors, Atkins received 14 Grammy Awards as well as the Grammy Lifetime Achievement Award, nine Country Music Association Instrumentalist of the Year awards, and was inducted into the Country Music Hall of Fame and Museum.

Paul Frederic Simon (born October 13, 1941) is a grammy award winning American singer-songwriter, poet and guitarist.

Simon's international fame and success began as part of the duo Simon & Garfunkel, launched in 1964 with musical partner Art Garfunkel. Simon wrote most of the pair's songs, including three that reached No. 1 on the U.S. singles charts: "The Sound of Silence", "Mrs. Robinson", and "Bridge Over Troubled Water". The duo split up in 1970 at the height of their popularity, and Simon began a successful solo career, recording three highly acclaimed albums over the next five years. In 1986, he released Graceland, an album inspired by South African township music. Simon also wrote and starred in the film One-Trick Pony in 1980 and co-wrote the Broadway musical The Capeman in 1998.

Simon has earned 12 Grammys for his solo and collaborative work, including the Lifetime Achievement Award. In 2001, he was inducted into the Rock and Roll Hall of Fame and in 2006 was selected as one of the "100 People Who Shaped the World" by Time magazine. Among many other honors, Simon was the first recipient of the Library of Congress' Gershwin Prize for Popular Song in 2007. In 1986 Simon was awarded an Honorary Doctor of Music degree from Berklee College of Music where he currently serves on the Board of Trustees.
