A Postludium is a postlude, originally music played as the congregation exited after a church service.

Although the key is C major, it begins with a subdominant IV chord and descends repetitively, making the tonality ambiguous until the end of the section. Section b, in contrast, generally ascends. In this section, the hands appear to be inverted compared to section a, with the right hand playing a melody line that ascends by step using a combination of half notes and quarter notes, against the left hand's Alberti bass.

The beautiful, varied harmonies within the horizontal flow of ascending and descending motion are reminiscent of the famous Prelude No. 1 from Bach's Well-Tempered Clavier, Book I. At the conclusion of the coda, the subdominant IV chord is used, bringing a gentle conclusion.
