A rap opera or hip hopera or sometimes urban opera is a musical work in hip hop style with operatic form.

Hip hop or hip-hop is a subculture and art movement developed in South Bronx in New York City during the late 1970s.
 While people unfamiliar with hip hop culture often use the expression "hip hop" to refer exclusively to hip hop music (also called "rap"), Hip hop is characterized by nine distinct elements or expressive realms, of which hip hop music is only four elements (rapping, djaying, beatboxing and breaking).
 Afrika Bambaataa of the hip hop collective Zulu Nation outlined the pillars of hip hop culture, coining the terms: "rapping" (also called MCing or emceeing), a rhythmic vocal rhyming style (orality); DJing (and turntablism), which is making music with record players and DJ mixers (aural/sound and music creation); b-boying/b-girling/breakdancing (movement/dance); and graffiti art, which he called "aerosol writin'", although many say that the graffiti that hip hop adopted had been around years earlier, and had nothing to do with hip hop culture.
 (visual art).
 Other elements of hip hop subculture and arts movements beyond the main four are: hip hop culture and historical knowledge of the movement (intellectual/philosophical); beatboxing, a percussive vocal style; street entrepreneurship; hip hop language; and hip hop fashion and style, among others.
Meren(gue)house/Merenrap is a hip hop music style formed by blending Dominican merengue music with rap, dancehall reggae and hip hop.
 The group Proyecto Uno pioneered the genre.
 Merenhouse usually combines a rap style of singing (talk-singing) with actual singing.
 It has instruments that are typically in merengue music, such as saxophones, trumpets, accordion, bass, guitar, güira, tambora (drum).
 However, they can be combined with electronic sounds or even electronic sounds sampled from the actual instruments (musch like house music).
 Sampling music means to take a sample or portion of a sound recording to reuse it in a song.
 Merenhouse is very upbeat for dancing, like house music.
 It is hard to identify merenhouse based on its time signature and rhythm alone.
 Some merenhouse music is in a fast 2/4 beat and has typical merengue style rhythms.
 Some also is in a slower 4/4 beat, identifying more with the hip hop style.
 Merenhouse can be characterized mostly by the instruments/electronics used and the combination of vocal styles.
Hip hop music in Washington, D.C. has been an important part of the culture of the area.
 The traditional style of hip hop in the city has been described as not quite the same as New York City hip hop and not quite the same as Southern hip hop.
 Rather, it has been influenced by both regions to form its own unique style of music.
 The population of D.C. is not large enough to support as many distinct subgenres of rap as other metropolitan areas, and as a result, the sound and style of D.C. hip hop is very mixed and blended.
 Prominent D.C. based hip hop artists include Wale, Oddisee, Fat Trel, Shy Glizzy, Lightshow, Ant Glizzy, Percy Jonez & Santino Ranks of YNWV and a few newcomers , GoldLink, Chaz French & Jay IDK.
 Many of these newcomers are typically featured on local radio stations such as 93.9 WKYS.
