The Real Book refers to compilations of lead sheets for jazz standards. It usually refers to the first volume of a series of books transcribed and collated by Berklee College of Music students during the 1970s.The name is derived from "fake books", so called because they contained only rough outlines of music pieces rather than fully notated scores. Early fake books were often used by professional bands who performed mostly standards, often more geared to society and dance bands rather than jazz ensembles, and devoted much space to show tunes, novelty tunes, traditional jazz, etc. The first three Real Book volumes, in contrast, contained many bebop and other jazz standards that were likely to be encountered on jazz gigs at the time. For this reason, the books were quickly adopted among jazz players in the 1970s, particularly on the east coast.
