Does this answer the question???
Rhythm and blues, often abbreviated to R&B and RnB, is a genre of popular African-American music that originated in the 1940s The term was originally used by record companies to describe recordings marketed predominantly to urban African Americans, at a time when "urbane, rocking, jazz based music with a heavy, insistent beat" was becoming more popular
The term has subsequently had a number of shifts in meaning. In the early 1950s, the term rhythm and blues was frequently applied to blues records.[3] Starting in the mid-1950s, after this style of music contributed to the development of rock and roll, the term "R&B" became used to refer to music styles that developed from and incorporated electric blues, as well as gospel and soul music. By the 1970s, rhythm and blues was used as a blanket term for soul and funk. In the 1980s, a newer style of R&B developed, becoming known as "Contemporary R&B".
Soul music is a combination of R&B and gospel and began in the late 1950s in the United States. Soul differentiates from R&B due to Soul music's use of gospel-music devices, its greater emphasis on vocalists and its merging of religious and secular themes.
Soul music can find its roots in 4 different sources: racial, geographical, historical and economical. The 1950s recordings of Sam Cooke, Ray Charles and James Brown are commonly considered the beginnings of soul music. There are many different types of Soul music, including, but not limited to: Southern Soul, Neo-Soul and Psychedelic Soul (which paved the way for Funk music in the 1960s. Soul music was born in Memphis and more widely in the southern US where most of the performing artists were from.
More than any other genre of popular American music, Soul is the result of the combination and merging of previous styles and sub-styles in the 1950s and 60s. Broadly speaking, soul comes from a gospel (the sacred) and blues (the profane). Blues was mainly a musical style that praised the fleshly desire whereas gospel was more oriented toward spiritual inspiration.
Once it gained popularity, Soul gradually came into white musical groups and was then called "Blue-Eyed Soul." Soul music ruled the black musical charts throughout the 1960s and inspired many other music styles such as current pop music and funk. In fact it never went away, it simply evolved.
