Makropterosuus, a single movement composition for full orchestra, is approximately sixteen minutes in duration. The work is scored for piccolo, two flutes, two oboes, two clarinets in B-flat, two tenor trombones, bass trombone, tuba, percussion, and strings. The composition of Makropterosuus involved the development of specialized computational procedures for the generation of melodic and rhythmic data.

Sound Study is a composition for large symphony orchestra in the twelve-tone idiom. It is a one-movement, monothematic piece in a large ternary form. The main body of the work is preceded by a long introduction which includes statements of the single thematic idea. The A section of the piece is scherzo-like in character and in a moderate 6/8 tempo. The theme is announced and receives a variety of treatment in this section. The B section is an extensive development of thematic material and utilizes a reverberation effect to be discussed below. A brief return of the A section brings the piece to a close.

The two purpose of this paper are to present an abbreviated study of the following three movements for orchestra, and to examine two different aspects of serial techniques used in the first and last movements respectively. Each movement is basically in the same A B A form; each, however, represents an entirely different approach to composition. Of course there are areas common to all three movements (melodic content, fragmentation, orchestration), and it is hoped that a stylistic continuity is maintained.
