Prelude and Fugue

It is a musical composition for solo piano which seeks to make references to some purely structural details, which Claude Debussy had in mind when writing some parts of his Preludes for piano, and which J. S. Bach used in some fragments of his Fugues for clavicembalo in his work The Well-Tempered Clavier.

For example, in the Prelude, there are frequent double (and even triple) motivic consecutive utterances;. There are also frequent sequences of chord structures that develop in parallel, or even contrary motion, or appear as triad chords overlays which can be understood as differing tonalities. The latter is another example of a technical resource which Debussy develops in some occasions, when writing some parts of his Preludes for solo piano.

On the other hand, in the Fugue, the exposition of a four-voice fugue is presented, after which the fragments are written in a divertimento or estretto, which seek to take into account the principles of construction through which J. S. Bach writes similar passages in his Fugues written for 4 voices of The Well-Tempered Clavier.
