What “realbook” means
WikipediaThe Real Book is a compilation of lead sheets for jazz standards. It was created in the mid-1970s by two students at the Berklee College of Music. In its original form, it was an illegal publication made at local copy shops. It quickly became a standard reference for musicians. Two additional volumes were bootlegged in subsequent decades.
