Analysis
[edit]Prelude
[edit]The prelude is in common time and has 50 measures, built upon the characteristic arpeggios similar to the famous C major prelude from the first book of The Well-Tempered Clavier until the fugato.[1]

Fugue
[edit]The fugue has three voices and 35 measures.[1] The subject is simply made from notes from the major triad, but has mutated many times throughout the whole fugue.[2]
