For solo piano, seven movements (2007) 16:45

The title Exordium references the beginning or introductory part of a discourse.  The composition, written for solo piano, is a set of variations based on the Sarabande movement from the keyboard Partita in B flat Major by JS Bach. Considering Bach to be seminal, the title for this group of variations seems appropriate.

Transmutation as a variation principle, borrowing from both plastic and literary arts, generates the fundamental structures of these nine compositional studies or etudes for solo piano.  Moving from historically accepted development and transformation, to complete transmutation (conversion or transferal of unlike elements), results in musical analogs for information control principles normally not considered indigenous to music.

Recollections of Childhood is a composite of early influences from study as a pianist.  Though the memories are altered by attitudes and inclinations acquired by the time of writing, the music contains images from a devotion to sources not atypical of impressionable young pianists. 

This etude for solo piano is derived from two contrasting and yet similar musical “sources.” The opening statement is an exposure of twelve notes taken from Johann Sebastian Bach's Prelude I from Book II of The Well Tempered Clavier. This is immediately followed by a collection of notes quoted from the opening fanfare of Arnold Schoenberg’s A Survivor from Warsaw. The interplay of the two quoted materials produces another level of musical possibilities unique to this study.
