Orchestral sketches are written quickly. The scoring for my fourth opera, Οιδιπους Τυραννος includes two orchestral harps, which in these first few sketches, play generally in unison. I should mention, that, for me, this site is a composition tool, which helps me organize my materials, while allowing friends and curious public the opportunity to check on my opera's progress. My preferred method -- and there are no textbooks on opera writing -- is to divide my opera into scenes. I consider every scene as a "slot," and I fill slots with music -- my music sketches. Ideally, the sketches fulfill the dramatic and emotional requirements of the scene. But many times, a sketch will not be a scene, but a theme, or represent an important dramatic event. A scene will typically incorporate two, three, or more sketches. When all my scene slots are filled, I then go back and begin to shape the music and begin to incorporate the libretto text. Because at this stage, I give the text predominance, the music sketches can change, and be altered drastically. My third opera, "Cancer Ward," is based on the book by the same name by Alexander Solzhenitsyn. The libretto is in Russian. I have most recently started my seventh opera, "Antigone," by Sophocles, using the original text in Classical Greek, for a libretto.
