This music is a Piano 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 but it is also very popular as a Guitar work. Since it is in two voices throughout, it is readily played as a piano work and is easily adapted to be played as a duet for various instruments.
