Violin

The violin is a string instrument in the violin family. It is the smallest and highest-pitched instrument in the family in regular use. The violin typically has four strings tuned in perfect fifths, and is most commonly played by drawing a bow across its strings. Violins are important instruments a wide variety of musical genres. They are most prominent in the Western classical tradition and in many varieties of folk music (where the violin is often known as the "fiddle"). However, violins are also frequently used in jazz, a number of different forms of rock and roll and metal, and descendants of folk including country music and bluegrass music. Further, the violin has come to be played in many non-Western music cultures all over the world. The violin is sometimes informally called a fiddle, regardless of the type of music played on it.

The violin was first known in 16th-century Italy, with some further modifications occurring in the 18th and 19th centuries. In Europe it served as the basis for stringed instruments used in western classical music, the viola and the violin. Violinists and collectors particularly prize the instruments made by the Stradivari, Guarneri and Amati families from the 16th to the 18th century in Brescia and Cremona and by Jacob Stainer in Austria. According to their reputation, the quality of their sound has defied attempts to explain or equal it, though this belief is disputed. Great numbers of instruments have come from the hands of "lesser" makers, as well as still greater numbers of mass-produced commercial "trade violins" coming from cottage industries in places such as Saxony, Bohemia, and Mirecourt. Many of these trade instruments were formerly sold by Sears, Roebuck and Co. and other mass merchandisers.

Hip hop

Hip hop or hip-hop is a sub-cultural movement that formed during the early 1970s by African-American and Puerto Rican youths residing in the South Bronx in New York City. It became popular outside of the African-American community in the late 1980s and by the 2000s became the most listened-to musical genre in the world. It is characterized by four distinct elements, all of which represent the different manifestations of the culture: rap music (oral), turntablism or DJing (aural), b-boying (physical) and graffiti art (visual). Even while it continues to develop globally in myriad styles, these four foundational elements provide coherence to hip hop culture. The term is often used in a restrictive fashion as synonymous only with the oral practice of rap music.

The origin of the hip hop culture stems from the block parties of the Ghetto Brothers, when they plugged in the amplifiers for their instruments and speakers into the lampposts on 163rd Street and Prospect Avenue and used music to break down racial barriers, and from DJ Kool Herc at 1520 Sedgwick Avenue, where Herc mixed samples of existing records with his own shouts to the crowd and dancers. Kool Herc is credited as the "father" of hip hop. DJ Afrika Bambaataa of the hip hop collective Zulu Nation outlined the pillars of hip hop culture, to which he coined the terms: MCing or "Emceein", DJing or "Deejayin", B-boying and graffiti writing or "Aerosol Writin".
