Hot or HOT may refer to:

Hip hop is a form of musical expression and artistic subculture that originated in African-American and Hispanic-American communities during the 1970s in New York City, specifically within the Bronx. The term often refers to hip hop music, which consists of poetry that is spoken - rather than sung - over either original or sampled instrumental recordings mixed with new original sounds from drum machines, and/or other instruments. However, the culture has expanded far beyond its original roots, and now is considered a worldwide subculture comprising rapping, DJing, hip hop dance, and graffiti art - known collectively as "Four Pillars of Hip Hop".

The block parties of DJ Kool Herc at 1520 Sedgwick Avenue, where Herc would mix samples of existing records with his own shouts to the crowd and dancers, are generally considered the birthplace of hip hop. Kool Herc is credited as the 'father' of the art form. DJ Afrika Bambaataa of the hip-hop collective Zulu Nation outlined the four pillars of hip hop culture: MCing, DJing, B-boying and graffiti writing. Since its emergence in the South Bronx, hip hop culture has spread to both urban and suburban communities throughout the world.Hip hop music first emerged with Kool Herc and contemporary disc jockeys and imitators creating rhythmic beats by looping breaks (small portions of songs emphasizing a percussive pattern) on two turntables, more commonly referred to as sampling. This was later accompanied by "rap", a rhythmic style of chanting or poetry presented in 16 bar measures or time frames, and beatboxing, a vocal technique mainly used to imitate percussive elements of the music and various technical effects of hip hop DJ's. An original form of dancing and particular styles of dress arose among fans of this new music. These elements experienced considerable refinement and development over the course of the history of the culture.

In music, a song is a composition for voice or voices, performed by singing. A song may be accompanied by musical instruments, or it may be unaccompanied, as in the case of a cappella songs. The lyrics (words) of songs are typically of a poetic, rhyming nature, though they may be religious verses or free prose.

A song may be for a solo singer, a duet, trio, or larger ensemble involving more voices. Songs with more than one voice to a part are considered choral works. Songs can be broadly divided into many different forms, depending on the criteria used. One division is between "art songs", "pop songs", and "folk songs". Other common methods of classification are by purpose (sacred vs secular), by style (dance, ballad, Lied, etc.), or by time of origin (Renaissance, Contemporary, etc.).

A song is a piece of music for accompanied or unaccompanied voice or voices or, "the act or art of singing," but the term is generally not used for large vocal forms including opera and oratorio. However, the term is, "often found in various figurative and transferred sense (e.g. for the lyrical second subject of a sonata...)." The noun "song" has the same etymological root as the verb "to sing" and the Oxford English Dictionary (OED) defines the word to mean "that which is sung" or "a musical composition suggestive of song." The OED also defines the word to mean "a poem" or "the musical phrases uttered by some birds, whales, and insects, typically forming a recognizable and repeated sequence and used chiefly for territorial defence or for attracting mates."
