Rapping (or rhyming, spitting, emceeing, MCing) is a musical form of vocal delivery that incorporates “rhyme, rhythmic speech, and street vernacular”, which is performed or chanted in a variety of ways, usually over a backing beat or musical accompaniment. The components of rap include “content” (what is being said), “flow” (rhythm, rhyme), and “delivery” (cadence, tone). Rap differs from spoken-word poetry in that rap is usually performed in time to an instrumental track. Rap is often associated with, and is a primary ingredient of hip-hop music, but the origins of the phenomenon predate hip-hop culture. The earliest precursor to the modern rap is the West African griot tradition, in which “oral historians”, or “praise-singers”, would disseminate oral traditions and genealogies, or use their formidable rhetorical techniques for gossip or to “praise or critique individuals.” Griot traditions connect to rap along a lineage of Black verbal reverence that goes back to ancient Egyptian practices, through James Brown interacting with the crowd and the band between songs, to Muhammad Ali’s quick-witted verbal taunts and the palpitating poems of the Last Poets. Therefore, rap lyrics and music are part of the “Black rhetorical continuum”, and aim to reuse elements of past traditions while expanding upon them through “creative use of language and rhetorical styles and strategies. The person credited with originating the style of “delivering rhymes over extensive music”, that would become known as rap, was Anthony “DJ Hollywood” Holloway from Harlem, New York.Rap is usually delivered over a beat, typically provided by a DJ, turntablist, beatboxer, or performed a cappella without accompaniment. Stylistically, rap occupies a gray area between speech, prose, poetry, and singing. The word, which predates the musical form, originally meant “to lightly strike”, and is now used to describe quick speech or repartee. The word had been used in British English since the 16th century. It was part of the African American dialect of English in the 1960s meaning “to converse”, and very soon after that in its present usage as a term denoting the musical style. Today, the term rap is so closely associated with hip-hop music that many writers use the terms interchangeably.

Electronic music is music that employs electronic musical instruments, digital instruments and circuitry-based music technology. In general, a distinction can be made between sound produced using electromechanical means (electroacoustic music), and that produced using electronics only. Electromechanical instruments include mechanical elements, such as strings, hammers, and so on, and electric elements, such as magnetic pickups, power amplifiers and loudspeakers. Examples of electromechanical sound producing devices include the telharmonium, Hammond organ, and the electric guitar, which are typically made loud enough for performers and audiences to hear with an instrument amplifier and speaker cabinet. Pure electronic instruments do not have vibrating strings, hammers, or other sound-producing mechanisms. Devices such as the theremin, synthesizer, and computer can produce electronic sounds.The first electronic devices for performing music were developed at the end of the 19th century, and shortly afterward Italian futurists explored sounds that had not been considered musical. During the 1920s and 1930s, electronic instruments were introduced and the first compositions for electronic instruments were made. By the 1940s, magnetic audio tape allowed musicians to tape sounds and then modify them by changing the tape speed or direction, leading to the development of electroacoustic tape music in the 1940s, in Egypt and France. Musique concrète, created in Paris in 1948, was based on editing together recorded fragments of natural and industrial sounds. Music produced solely from electronic generators was first produced in Germany in 1953. Electronic music was also created in Japan and the United States beginning in the 1950s. An important new development was the advent of computers to compose music. Algorithmic composition with computers was first demonstrated in the 1950s (although algorithmic composition per se without a computer had occurred much earlier, for example Mozart’s Musikalisches Würfelspiel).
In the 1960s, live electronics were pioneered in America and Europe, Japanese electronic musical instruments began influencing the music industry, and Jamaican dub music emerged as a form of popular electronic music. In the early 1970s, the monophonic Minimoog synthesizer and Japanese drum machines helped popularize synthesized electronic music.
In the 1970s, electronic music began having a significant influence on popular music, with the adoption of polyphonic synthesizers, electronic drums, drum machines, and turntables, through the emergence of genres such as disco, krautrock, new wave, synth-pop, hip hop and EDM. In the 1980s, electronic music became more dominant in popular music, with a greater reliance on synthesizers, and the adoption of programmable drum machines such as the Roland TR-808 and bass synthesizers such as the TB-303. In the early 1980s, digital technologies for synthesizers including digital synthesizers such as the Yamaha DX7 were popularized, and a group of musicians and music merchants developed the Musical Instrument Digital Interface (MIDI).
Electronically produced music became prevalent in the popular domain by the 1990s, because of the advent of affordable music technology. Contemporary electronic music includes many varieties and ranges from experimental art music to popular forms such as electronic dance music. Today, pop electronic music is most recognizable in its 4/4 form and more connected with the mainstream culture as opposed to its preceding forms which were specialized to niche markets.

A trap is a mechanical device used to capture or restrain an animal for purposes such as hunting, pest control, or ecological research.

Electropop is a music genre combining elements of electronic and pop genres. Usually, it is described as a variant of synth-pop with heavy emphasis on its electronic sound. The genre has seen a revival of popularity and major influence since the 2000s.

Underground hip hop is an umbrella term for hip hop music outside the general commercial canon. It is typically associated with independent artists, signed to independent labels or no label at all. Underground hip hop is often characterized by socially conscious, positive, or anti-commercial lyrics. However, there is no unifying or universal theme – AllMusic suggests that it “has no sonic signifiers”. “The Underground” also refers to the community of musicians, fans and others that support non-commercial, or independent music. Music scenes with strong ties to underground hip hop include alternative hip hop and conscious hip hop. Many artists who are considered “underground” today were not always so, and may have previously broken the Billboard charts.To gain fans, underground artists perform locally and worldwide, make tours, and meet and greets. Their performances are held anywhere, such as outdoors or in restaurants. Meet and greets are often held in different cities, which gives a fan the opportunity to meet the artist for free. There the fan can buy clothing from the artist’s clothing line or they can purchase tickets for future concerts. Ticket prices range depending on the location, some artists have VIP passes, allowing the fan to have access to the stage and to meet them after the show. Some artists make their own clothing line to sell gear and use the profit to continue making shows. Underground artists are usually found in YouTube, SoundClick, Bandcamp and SoundCloud. Lastly, underground artists typically do everything themselves whether it’s making songs, preparing shows, or selling gear.

Electronic dance music (EDM), also known as dance music, club music, or simply dance, is a broad range of percussive electronic music genres made largely for nightclubs, raves and festivals. It is generally produced for playback by disc jockeys who create seamless selections of tracks, called a mix by segueing from one recording to another. EDM producers also perform their music live in a concert or festival setting in what is sometimes called a live PA. In Europe, EDM is more commonly called ‘dance music’, or simply ‘dance’.In the late 1980s and early 1990s, following the emergence of raving, pirate radios and an upsurge of interest in club culture, EDM achieved widespread mainstream popularity in Europe. In the United States at that time, acceptance of dance culture was not universal; although both electro and Chicago house music were influential both in Europe and the United States, mainstream media outlets and the record industry remained openly hostile to it. There was also a perceived association between EDM and drug culture, which led governments at state and city level to enact laws and policies intended to halt the spread of rave culture.Subsequently, in the new millennium, the popularity of EDM increased globally, largely in Australia and the United States. By the early 2010s, the term “electronic dance music” and the initialism “EDM” was being pushed by the American music industry and music press in an effort to rebrand American rave culture. “Despite the industry’s attempt to create a specific EDM brand, the initialism remains in use as an umbrella term for multiple genres, including house, techno, trance, drum and bass, dubstep, and Trap music (EDM) as well as their respective subgenres.[5][6][7][8][9]”

Deep house is a subgenre of house music that originated in the 1980s, initially fusing elements of Chicago house with 1980s jazz-funk and touches of soul music. Its origins are attributed to Larry Heard’s track “Mystery of Love” in 1984.This style of house music can often have an acoustic feeling. The online music store Beatport is credited with driving the popularity of deep house, but also with mislabeling a number of artists in the process and with giving rise to the future house genre.

A house is a building that functions as a home. They can range from simple dwellings such as rudimentary huts of nomadic tribes and the improvised shacks in shantytowns to complex, fixed structures of wood, brick, concrete or other materials containing plumbing, ventilation, and electrical systems. Houses use a range of different roofing systems to keep precipitation such as rain from getting into the dwelling space. Houses may have doors or locks to secure the dwelling space and protect its inhabitants and contents from burglars or other trespassers. Most conventional modern houses in Western cultures will contain one or more bedrooms and bathrooms, a kitchen or cooking area, and a living room. A house may have a separate dining room, or the eating area may be integrated into another room. Some large houses in North America have a recreation room. In traditional agriculture-oriented societies, domestic animals such as chickens or larger livestock (like cattle) may share part of the house with humans. The social unit that lives in a house is known as a household.
Most commonly, a household is a family unit of some kind, although households may also be other social groups, such as roommates or, in a rooming house, unconnected individuals. Some houses only have a dwelling space for one family or similar-sized group; larger houses called townhouses or row houses may contain numerous family dwellings in the same structure. A house may be accompanied by outbuildings, such as a garage for vehicles or a shed for gardening equipment and tools. A house may have a backyard or frontyard, which serve as additional areas where inhabitants can relax or eat.
