HOW TO RAP: The Art and Science of the Hip-Hop MC
by Paul Edwards
Foreword by Kool G Rap
With a foreword by Kool G Rap (rap pioneer named as a major influence by Eminem and Jay-Z) and interviews with over 100 major MCs, "HOW TO RAP: The Art & Science of the Hip-Hop MC" guides the reader through the art form of rapping in the words of the artists, giving an inside look behind their creative processes and techniques. ...
HOW TO RAP breaks MCing down into content, flow, writing, and delivery with topics such as writing in your head, punching-in vocals, and interacting with the crowd all tackled from different angles by numerous pros.
The book also features the first complete breakdown of "flow", allowing readers to create tongue-twisting compound rhyme styles like Kool G Rap and Eminem, complex conversational flows like Nas, Jay-Z, and O.C., the classic old school patterns of Melle Mel, and everything in between.
A little-known fact about me: I "experimented" with this alternative lifestyle as a sixth-grader in the 1980s, with tragic results: silver-striped shell-top Adidas, neon argyle "thickies," parachute pants--the whole nine yard. A horrifying spectacle. It is safe to say that I was born without "flow" and that no book can confer it on me.
