I kind of got bored of imitating baroque style, so I included some unconventionally resolved sevenths and ninths because they contribute a more open sound; the modulation is a consequence of me trying to make the modulations in this fugue follow that from the opening of the prelude.
I wanted this fugue to be short, lightweight, and generally very open sounding (hence why it mostly only uses three voices and is registrated for 4' stops, which sound an octave higher than written). This is in stark contrast to the prelude, which is very dense, long, and convoluted.
