Bach uses a pedal point in the bass as well as an invertible counterpoint in the alto and tenor voices between measures 45 and 50. The development section does not modulate from the tonic key. There is a restatement of the fugue subject in the tonic in the bass voice in measure 63. This piece ends with a Perfect Authentic Cadence in the tonic key.
