In search for consistent realization of artistic ideas, coherence of musical fabric, projection of genuine emotion, the composer made use of expression means characteristic of both early (elements characteristic of Middle Ages and Renaissance music, such as intervals, voice leading) and contemporary music techniques (serialism, aleatory, repetitiveness, etc.), employed novel modal and rhythmic systems.
