“Greensleeves” also known by a lot of alternate names such as "Bliven's Favorite", "The Butchers of Bristol", "Coppers and Brass", "The County Limerick Buckhunt", "Lasses of Melross" and others is usually played in A minor.
The tune is a member of a large tune family. The jig was printed by Glasgow publisher James Aird in 1782 in Selection of Scotch, English, Irish and Foreign Airs, vol. 1 (1782), without mention of provenance. A broadside ballad by this name was registered at the London Stationer's Company in September 1580, by Richard Jones, as "A Newe Northen Dittye of ye Ladye Greene Sleves". Six more ballads followed in less than a year. It then appears in the surviving A Handful of Pleasant Delights (1584) as "Sonnet of the Lady Green Sleeves - To the new tune of Green Sleeves".
There is a persistent rumor that it was written by Henry VIII but there is no real evidence of this.
In Shakespeare's The Merry Wives of Windsor (written c. 1597; first published in 1602), the character Mistress Ford refers twice to "the tune of 'Greensleeves'" and Falstaff later exclaims "Let the sky rain potatoes! Let it thunder to the tune of 'Greensleeves'!" These allusions indicate the song was already well known at that time.
It was printed in Aird's Selection of Scotch, English, Irish and Foreign Airs, vol. 1 (1782), Joyce's Old Irish Folk Music and Song (1909), O'Flannagan's Hibernia Collection (1860), Ives's Burl Ives Song Book (1953) and many other publicatios.
This is not the "Greensleeves" tune used for dancing the "Bacca Pipes Jig" and some other sword or morris dances. A somewhat simplified version of this tune (usually set in E minor) is used for the Christmas carol "What Child is this?".
