Prelude and Fugue in D major - (2010)
The baroque and classic eras made scales as objects of musical invention, and the parallelism of later periods added the possibility of these pre-compositional elements combining. For this the theme of this prelude in D major is a D major scale, accompanied in part by the simplest of triadic harmony under an ornamented tonic pedal in the top voice. A similar gambit is at measure 18 and beyond without the succession between D and Em, as the tonic triad is now the pedal broken into arpeggios.
The fugue subject rightly may be noted in 6/16, as the duple division of three eighths, but subsequent pedal entrances shift the emphasis, as do some counterpoint. Two final statement of the subject in the pedal occur, first as sixteenths and then in augmentation as the opening gambit of the prelude is joined with it.
