Traditional pop in the context of "Acoustic music"

The Nashville sound is a subgenre of American country music that originated in the 1950s in Nashville, Tennessee. It replaced the dominance of the rough honky tonk music with "smooth strings and choruses", "sophisticated background vocals" and "smooth tempos" associated with traditional pop. It was an attempt "to revive country sales, which had been devastated by the rise of rock 'n' roll".

The Beatles were an English rock band formed in Liverpool in 1960. The core lineup of the band comprised John Lennon, Paul McCartney, George Harrison and Ringo Starr. They are widely regarded as the most influential band in popular music and were integral to the development of 1960s counterculture and the recognition of popular music as an art form. Rooted in skiffle, beat and 1950s rock 'n' roll, their sound incorporated elements of classical music and traditional pop in innovative ways. The band also explored music styles ranging from folk and Indian music to psychedelia and hard rock. As pioneers in recording, songwriting and artistic presentation, the Beatles revolutionised many aspects of the music industry and were often publicised as leaders of the era's youth and sociocultural movements.

Led by primary songwriters Lennon and McCartney, the Beatles evolved from Lennon's previous group, the Quarrymen, and built their reputation by playing clubs in Liverpool and Hamburg, Germany, starting in 1960. The core trio of Lennon, McCartney and Harrison, together since 1958, went through a succession of drummers before inviting Starr to join them in 1962. Manager Brian Epstein moulded them into a professional act, and producer George Martin developed their recordings, greatly expanding their domestic success after they signed with EMI and achieved their first hit, "Love Me Do", in late 1962. As their popularity grew into the intense fan frenzy dubbed "Beatlemania", the band acquired the nickname "the Fab Four". By early 1964, the Beatles were international stars and had achieved unprecedented levels of critical and commercial success. They became a leading force in Britain's cultural resurgence, ushering in the British Invasion of the United States pop market. They soon made their film debut with A Hard Day's Night (1964).

The United States' multi-ethnic population is reflected through a diverse array of styles of music. It is a mixture of music influenced by the music of Europe, Indigenous peoples, West Africa, Latin America, Middle East, North Africa, amongst many other places. The country's most internationally renowned genres are traditional pop, jazz, blues, country, bluegrass, rock, rock and roll, R&B, pop, hip-hop, soul, funk, religious, disco, house, techno, ragtime, doo-wop, folk, americana, boogaloo, tejano, surf, and salsa, amongst many others. American music is heard around the world. Since the beginning of the 20th century, some forms of American popular music have gained a near global audience.

Native Americans were the earliest inhabitants of the land that is today known as the United States and played its first music. Beginning in the 17th century, settlers from the United Kingdom, Ireland, Spain, Germany, and France began arriving in large numbers, bringing with them new styles and instruments. Enslaved people from West Africa brought their musical traditions, and each subsequent wave of immigrants contributed to a melting pot.

Beat music, British beat, or Merseybeat is a British popular music genre that developed around Liverpool in the late 1950s and early 1960s. The genre melded influences from British and American rock and roll, rhythm and blues, skiffle, traditional pop, and music hall. It rose to mainstream popularity in the United Kingdom and Europe by 1963 before spreading to North America in 1964 with the British Invasion. The beat style shaped popular music and youth culture through 1960s movements such as garage rock, folk rock and psychedelic music.

The Great American Songbook is the loosely defined canon of significant 20th-century American jazz standards, popular songs, and show tunes.

A concept album is a musical album whose tracks hold a larger purpose or meaning collectively than they do individually. This is typically achieved through a single central narrative or theme, which can be instrumental, compositional, or lyrical. Alternatively, the term may signify an album that lacks any explicit musical or lyrical motif, but is considered to be of "uniform excellence". Music critics remain divided on the precise definition of a concept album.

The format originates with folk singer Woody Guthrie's Dust Bowl Ballads (1940) and was subsequently popularized by traditional pop singer Frank Sinatra's 1940s–50s string of albums, though the term is most closely associated with rock music. In the 1960s, various rock bands released several well-regarded concept albums, eventually leading to the birth of the rock opera.

Judith Marjorie Collins (born May 1, 1939) is an American singer-songwriter and musician with a career spanning nearly seven decades. An Academy Award-nominated documentary director and a Grammy Award-winning recording artist, she is known for her eclectic tastes in the material she records (which has included folk music, country, show tunes, pop music, rock and roll and standards), for her social activism, and for the clarity of her voice. Her discography consists of 36 studio albums, nine live albums, numerous compilation albums, four holiday albums, and 21 singles.

Collins' debut studio album, A Maid of Constant Sorrow, was released in 1961 and consisted of traditional folk songs. She had her first charting single with "Hard Lovin' Loser" (No. 97) from her fifth studio album In My Life (1966), but it was the lead single from her sixth studio album Wildflowers (1967), "Both Sides, Now" – written by Joni Mitchell – that gave her international prominence. The single reached No. 8 on the Billboard Pop Singles chart and won Collins her first Grammy Award for Best Folk Performance. She enjoyed further success with her recordings of "Someday Soon", "Chelsea Morning" (also written by Mitchell), "Amazing Grace", "Turn! Turn! Turn!", and "Cook with Honey".

The Beach Boys are an American rock band formed in Hawthorne, California, in 1961. The group's original lineup consisted of brothers Brian, Dennis, and Carl Wilson, their cousin Mike Love, and their friend Al Jardine. Distinguished by their vocal harmonies, adolescent-oriented lyrics, and musical ingenuity, they are one of the most influential acts of the rock era. The group drew on the music of older pop vocal groups, 1950s rock and roll, and black R&B to create their unique sound. Under Brian's direction, they often incorporated classical or jazz elements and pioneered unconventional recording techniques in innovative ways.

They formed as a garage band centered on Brian's songwriting and managed by the Wilsons' father, Murry. Jardine was briefly replaced by David Marks during 1962–1963. In 1962, they enjoyed their first national hit with "Surfin' Safari", beginning a string of hit singles that reflected a southern California youth culture of surfing, cars, and romance, dubbed the "California sound". They were one of the few American rock bands to sustain their commercial standing during the British Invasion. 1965 saw the addition of Bruce Johnston to the band, as well as Brian's move away from beach-going themes for more introspective lyrics and ambitious studio productions. In 1966, the Pet Sounds album and "Good Vibrations" single raised the group's prestige as rock innovators; both are now widely considered to be among the greatest and most influential works in popular music history.
