Hip hop historians sometimes disagree about the exact numbers of “pillars” of hip hop, but all agree there are core elements and principles that unite the culture. We’ll go with five.
— B-boying: Acrobatic dancing on the street (also known as B-Girling, Breaking).
— Graffiti, including TAGGING: drawing or spraying designs in a public place.
— MCing: expression through insightful rap or lyrics
— DJing: Spinning/SCRATCHING/mixing music, originally using records and a turntable.
— KNOWLEDGE: A broad consciousness that binds all the elements of hip hop together.
