Being of Illusion and Death is a high-modernist work that uses wide-spanning chords and shifting dynamics to create a sense of existential tension. The music is characterized by its unconventional harmonic language and dramatic shifts in intensity.
Mastering the large, wide-span chords while maintaining precise dynamic control is the primary challenge.
