With only a few very simple stylistic guidelines, the performer interprets the pitches he sees and how they are presented to him. With the computer as partial composer handling note selection, processing, and stylistic choices, my role has become the creator of the system out of which the composition arises. Guidelines are set for the musical decisions and framework for the structure of the piece so that no matter what the computer chooses to do, the work will unfold somewhat in the manner that was envisioned. This Nocturne is composed as a series of Vigils - defined as “a period of purposeful sleeplessness, an occasion for devotional watching, or an observance.” It was composed during the impending arrival of a friend's first child. As such, it is dedicated to the best of all sleepless nights.  > Nocturne Album Cover
