DJing is the technique of manipulating sounds and creating music using Phonographic Turntables and a DJ mixer One of the first DJ's was Kool DJ Herc, who created hip hop through the isolation of "breaks" (the parts of albums that focused solely on the beat). In addition to developing Herc's techniques, DJs Grandmaster Flowers, Grandmaster Flash, Grandmaster Wizard Theodore and Grandmaster Caz made further innovations introducing Sratching. Traditionally, a DJ will use two Turntables simultaneously. These are connected to a DJ mixer, an Amplifier, Speakers And numerous other types of electronic equipment. The DJ will then perform various tricks between the two albums currently in rotation using the above listed methods. The result is a unique sound created by the seemingly combined sound of two separate songs into one song. Although there is considerable overlap between the two roles, a DJ is not the same as a producer of a music track.Edit
MCing Rapping (also known as emceeing, MCing, spitting (bars), or just rhyming) refers to "spoken or chanted rhyming lyrics with a strong rhythmic accompaniment". It can be broken down into different components, such as “content”, “flow” (rhythm and rhyme), and “delivery”. Rapping is distinct from spoke word poetry in that is it performed in time to the beat of the music. The use of the word "rap" to describe quick and slangy speech or repartee long predates the musical form. MCing is a form of expression that is embedded within ancient African culture and oral tradition as throughout history verbal acrobatics or jousting involving rhymes were common within the African American community.
Beatboxing popularized by Doug E.Fresh is the technique of vocal precussion It is primarily concerned with the art of creating beats, rhythms, and melodies using the human mouth. The term beatboxing is derived from the mimicry of the first generation of drum machines, then known as beatboxes. As it is a way of creating hip hop music, it can be categorized under the production element of hip hop, though it does sometimes include a type of rapping intersected with the human-created beat. It is generally considered to be part of the same "Pillar" of hip hop as DJ'ing - in other words, providing a musical backdrop or foundation for MC's to rhyme over. Beatboxing was quite popular in the 1980s with prominent artists like the Darren "Buffy, the Human Beat Box" Robinson of the Fat Boyz and Biz Markie displaying their skills within the media. It declined in popularity along with b-boying in the late 1980s, but has undergone a resurgence since the late '90s, marked by the release of "Make the Music 2000." by Rahzel of The Roots.
