Soul music is a popular music genre that originated in African American communities throughout the United States in the late 1950s and early 1960s. Catchy rhythms, stressed by handclaps and extemporaneous body movements, are an important hallmark of soul. Other characteristics are a call and response between the lead and backing vocalists, an especially tense vocal sound, and occasional improvisational additions, twirls, and auxiliary sounds. Soul music is known for reflecting African American identity and stressing the importance of African American culture.

Soul has its roots in African-American gospel music and rhythm and blues, and primarily combines elements of gospel, R&B and jazz. The genre emerged from the power struggle to increase black Americans' awareness of their African ancestry, as a newfound consciousness led to the creation of music that boasted pride in being black. Soul music became popular for dancing and listening, and American record labels such as Motown, Atlantic and Stax were influential in its proliferation during the civil rights movement. Soul also became popular worldwide, directly influencing rock music and the music of Africa. It had a resurgence in the mid-to late 1990s with the subgenre neo soul, which incorporated modern production elements and hip-hop influences.

Soul music dominated the U.S. R&B charts in the 1960s, and many recordings crossed over into the pop charts in the United States, United Kingdom, and elsewhere. Many prominent soul artists, including Ray Charles, Sam Cooke, Otis Redding, James Brown, Aretha Franklin, and various acts under the Motown label, such as the Supremes and the Temptations, were highly influential in the genre's development and all gained widespread popularity during this time. By 1968, the soul music genre had begun to splinter. Some soul artists moved to funk music, while other singers and groups developed slicker, more sophisticated, and in some cases more socially conscious varieties. By the early 1970s, soul music had begun to absorb influences from psychedelic rock and progressive rock, among other genres, leading to the creation of psychedelic soul and progressive soul. Prominent soul artists of this era include Marvin Gaye, Jackson 5, Stevie Wonder, Curtis Mayfield, Isaac Hayes, Al Green, and Bill Withers. Neo soul, which adopted hip-hop influences, emerged around 1994.

Other subgenres of soul include the "Motown sound", a more rhythmic and pop-friendly style that originated from the eponymous label; Southern soul, a driving, energetic variety combining R&B with southern gospel music influences; Memphis soul, a shimmering, sultry style; New Orleans soul, which emerged from the rhythm and blues style; Chicago soul, a lighter gospel-influenced sound; and Philadelphia soul, a lush orchestral variety with doo-wop-inspired vocals.

Soul music has its roots in traditional African-American gospel music and rhythm and blues and as the hybridization of their respective religious and secular styles – in both lyrical content and instrumentation – that began in the 1950s. The term "soul" had been used among African-American musicians to emphasize the feeling of being an African-American in the United States. According to musicologist Barry Hansen,

Though this hybrid produced a clutch of hits in the R&B market in the early 1950s, only the most adventurous white fans felt its impact at the time; the rest had to wait for the coming of soul music in the 1960s to feel the rush of rock and roll sung gospel-style.

According to AllMusic, "Soul music was the result of the urbanization and commercialization of rhythm and blues in the '60s." The phrase "soul music" itself, referring to gospel-style music with secular lyrics, was first attested in 1961. The term "soul" in African-American parlance has connotations of African-American pride and culture. Gospel groups in the 1940s and '50s occasionally used the term as part of their names. The jazz style that originated from gospel became known as soul jazz. As singers and arrangers began using techniques from both gospel and soul jazz in African-American popular music during the 1960s, soul music gradually functioned as an umbrella term for African-American popular music at the time.

According to the Acoustic Music Organization, the "first clear evidence of soul music shows up with the "5" Royales, an ex-gospel group that turned to R&B and in Faye Adams, whose "Shake A Hand" becomes an R&B standard".
