The typical Great American Songbook songs -- known in jazz, then as now, simply as "standards" -- were lushly orchestrated, romantic pop numbers, heavy on balladry, which would then be "interpreted" by singers of the day. As a result, many of the genre's songs exist in hundreds if not thousands of varied vocal and instrumental versions, their only constant being the lyrics and melody (although daring jazz instrumentalists and vocalists might even taken great liberties with those).
As vinyl records had not come into their own yet, these songs largely originated from two sources: the radio star, or "crooner," a direct antecedent of the teen idols who benefited from the new advances in microphone technology that let them sing quietly and in a more intimate fashion; and also Broadway and Hollywood musicals, which provided an outlet for standards right through the early Sixties. Though this music was largely killed off by the rock and roll explosion, it survives today in the jazz vocal world, and has recently made a pop comeback of sorts with the rise of American Idol and also Rod Stewart's string of #1 GAS albums.
