Soul music began in the late 1950s as a combination of R&B and gospel, emphasizing vocalists and merging religious and secular themes. It has roots in racial, geographical, historical, and economic sources. Recordings by Sam Cooke, Ray Charles, and James Brown in the 1950s are commonly considered the beginnings of soul music. Soul music was born in Memphis and the southern US, where most performing artists originated.

2. Soul
 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.

3. Pop
 Pop music (a term that originally derives from an
abbreviation of "popular") is usually understood to be
commercially recorded music, often oriented toward a
youth market, usually consisting of relatively short, simple
songs utilizing technological innovations to produce new
variations on existing themes. Pop music has absorbed
influences from most other forms of popular music, but as a
genre is particularly associated with the rock and roll and
later rock style.
 Hatch and Millward define pop music as "a body of music
which is distinguishable from popular, jazz and folk
musics". Although pop music is often seen as oriented
towards the singles charts it is not the sum of all chart
music, which has always contained songs from a variety of
sources, including classical, jazz, rock, and novelty
songs, while pop music as a genre is usually seen as existing
and developing separately.[2] Thus "pop music" may be used
to describe a distinct genre, aimed at a youth
market, often characterized as a softer alternative to rock
and roll.

4. Dance
 Dance music is music composed specifically to facilitate or
accompany dancing. It can be either a whole musical
piece or part of a larger musical arrangement. In terms of
performance, the major categories are live dance music
and recorded dance music.
 A new form of electronic dance music was developing. This
music, made using electronics, is a style of popular music
commonly played in dance music nightclubs, radio
stations, shows and raves. During its gradual decline in
the late 1970s, disco became influenced by
computerization. Looping, sampling and segueing as
found in disco continued to be used as creative techniques
within Trance music, Techno music, and especially House
music.
