HH meaning in Community ?

Hip hop or hip-hop is a culture and art movement that was created by African Americans, Latino Americans and Caribbean Americans in the Bronx, New York City. The origin of the name is often disputed. It is also argued as to whether hip hop started in the South or West Bronx. While the term hip hop is often used to refer exclusively to hip hop music (including rap), hip hop is characterized by four key elements: "rapping" (also called MCing or emceeing), a rhythmic vocal rhyming style (orality); DJing (and turntablism), which is the practice of making music with record players and DJ mixers (aural/sound and music creation); b-boying/b-girling/breakdancing (movement/dance); and graffiti. Other elements 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. The fifth element, although debated, is commonly considered either street knowledge, hip hop fashion, or beatboxing.

The Bronx hip hop scene emerged in the mid-1970s from neighborhood block parties thrown by the Black Spades, an African American group that has been described as being a gang, a club, and a music group. Brother-sister duo DJ Kool Herc and Cindy Campbell additionally hosted DJ parties in the Bronx and are credited for the rise in the genre. Hip hop culture has spread to both urban and suburban communities throughout the United States and subsequently the world. These elements were adapted and developed considerably, particularly as the art forms spread to new continents and merged with local styles in the 1990s and subsequent decades. Even as the movement continues to expand globally and explore myriad styles and art forms, including hip hop theater and hip hop film, the four foundational elements provide coherence and a strong foundation for hip hop culture. Hip hop is simultaneously a new and old phenomenon; the importance of sampling tracks, beats, and basslines from old records to the art form means that much of the culture has revolved around the idea of updating classic recordings, attitudes, and experiences for modern audiences. Sampling older culture and reusing it in a new context or a new format is called "flipping" in hip hop culture. Hip hop music follows in the footsteps of earlier African-American-rooted and Latino musical genres such as blues, jazz, rag-time, funk, salsa, and disco to become one of the most practiced genres worldwide.

In the 2000s, with the rise of new media platforms such as online music streaming services, fans discovered and downloaded or streamed hip hop music through social networking sites beginning with Blackplanet & Myspace, as well as from websites like YouTube, Worldstarhiphop, SoundCloud, and Spotify.
