Show tune in the context of "Hamilton (musical)"

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. Many are originally Tin Pan Alley popular songs, Broadway show tunes or songs from Hollywood musicals – the Great American Songbook. In Europe, jazz standards and "fake books" may even include some traditional folk songs (such as in Scandinavia) or pieces of a minority ethnic group's music (such as Romani music) that have been played with a jazz feel by well known jazz players. A commonly played song can only be considered a jazz standard if it is widely played among jazz musicians. The jazz standard repertoire has some overlap with blues and pop standards.

The Great American Songbook is the loosely defined canon of significant 20th-century American jazz standards, popular songs, and show tunes.

Judith Marjorie Collins (born May 1, 1939) is an American singer-songwriter and musician with a career spanning nearly seven decades. An Academy Award-nominated documentary director and a Grammy Award-winning recording artist, she is known for her eclectic tastes in the material she records (which has included folk music, country, show tunes, pop music, rock and roll and standards), for her social activism, and for the clarity of her voice. Her discography consists of 36 studio albums, nine live albums, numerous compilation albums, four holiday albums, and 21 singles.

Collins' debut studio album, A Maid of Constant Sorrow, was released in 1961 and consisted of traditional folk songs. She had her first charting single with "Hard Lovin' Loser" (No. 97) from her fifth studio album In My Life (1966), but it was the lead single from her sixth studio album Wildflowers (1967), "Both Sides, Now" – written by Joni Mitchell – that gave her international prominence. The single reached No. 8 on the Billboard Pop Singles chart and won Collins her first Grammy Award for Best Folk Performance. She enjoyed further success with her recordings of "Someday Soon", "Chelsea Morning" (also written by Mitchell), "Amazing Grace", "Turn! Turn! Turn!", and "Cook with Honey".
