This music is a Guitar version of the Bourrée in E minor from the Lute Suite (also in E minor, BWV 996) by Johann Sebastian Bach. A Bourrée is a type of dance music and it is commonly included within Baroque Suites. This particular Bourrée was originally written for the Lute though it is frequently played and very popular as a Guitar work. On mfiles you can also find alternative versions of the Bourrée for Piano or other Keyboard instrument and our Duet Version which includes parts for different instruments and combinations. The piece has also been covered and adapted by many artists, most famously by Jethro Tull under the title "Bourée" and included on their album "Stand Up".
