Jazz standard

Jazz standards are musical compositions that are an important part of the musical repertoire of jazz musicians, in that they are widely known, performed, and recorded by jazz musicians, and widely known by listeners. There is no definitive list of jazz standards, and the list of songs deemed to be standards changes over time. Songs included in major fake book publications (lead sheet collections of popular tunes) and jazz reference works offer a rough guide to which songs are considered standards. Not all jazz standards were written by jazz composers.
