Reggae is a music genre first developed in Jamaica in the late 1960s.

While sometimes used in a broader sense to refer to most types of Jamaican music, the term reggae more properly denotes a particular music style that originated following on the development of ska and rocksteady. Reggae is based on a rhythm style characterized by regular chops on the off-beat, known as the skank. The tempo is generally slower than that found in ska. Reggae usually has accents on the 3rd beat in each bar, there being four beats in a bar; many people think it's accentuated on the 2nd and 4th, because of the rhythm guitar.

Disco is a genre of dance-oriented music whose origins are hard to define. In what is considered a forerunner to disco style clubs in February 1970 New York City DJ David Mancuso opened The Loft, a members-only private dance club set in his own home. Most agree that the first disco songs were released in 1973, though some claim Manu Dibango's 1972 Soul Makossa to be the first disco record. The first article about disco was written in September 1973 by Vince Aletti for Rolling Stone Magazine. In 1974 New York City's WPIX-FM premiered the first disco radio show

Hip hop is a cultural movement which developed in New York City in the 1970s primarily among African Americans. Its four main elements are rapping, DJing, graffiti, and b-boying (breakdancing). Other elements include beatboxing, hip hop fashion, and slang. Since first emerging in The Bronx, the lifestyle of hip hop culture has spread around the world.
When hip hop music began to emerge, it was based around DJs who created rhythmic beats by looping breaks (smalls portions of songs emphasizing a percussive pattern) on two turntables. This was later accompanied by "rapping" (a rhythmic style of chanting). An original form of dancing, and particular styles of dress, arose among followers of this new music. These elements experienced considerable refinement and development over the course of the history of the culture.
