"The Great American Songbook is a hypothetical construct that seeks to represent the best American songs of the 20th century principally from Broadway theatre, musical theatre, and Hollywood musicals, from the 1920s to 1960, including dozens of songs of enduring popularity. The Great American Songbook became (and remains) a vital part of the repertoire of jazz musicians, who describe such songs simply as "jazz standards"."
