Date: circa 1709

What we want you to remember about this composition:
- Listen to how Bach weaves and overlaps the subject throughout the piece.
Other things to listen for
- The subject (tune) is introduced in the highest voices and then is imitated in each lower voice in order: soprano, alto, tenor and then bass in the pedals. After the exposition is completed in the bass pedals, the subject is introduced in the first voice. Upon the entrance of the second layer, the first voice goes into a counter subject. Just before the subject is introduced five more times, it is preceded by a brief episode. In each episode the subject is not played in its entirety.
- Even though the fugue is in G minor, the piece ends with a major chord, a practice utilized during the Baroque period. Major chords were thought more conclusive than minor chords.
