Asimina Katerini

''Tetraktys'' is divided into two categories, or "worlds." The first category, or "world," assigned to the string instruments, is centered on the Monad, the single note (first and third movements). Here, the concept of the Monad symbolizes the metaphysical and the unknowable, the coexistence of Good and Evil, as well as the higher cosmic consciousness, the Divine, and the Infinite. The second category, or "world," entrusted to the wind instruments, gradually unfolds as each instrument enters, eventually presenting all twelve pitches. It symbolizes the material world: mortality, sin, and humankind. The human dimension of the work is expressed through the tragic nature of human existence, earthly passions, suffering, and death. In essence, Tetraktys symbolizes humanity's opening toward—and attunement with—another dimension, the Universe itself. The work incorporates the Orphic Hymn to Uranus.

''Emmoni'' (Obsession)

Asimina Katerini – Emmoni (Obsession) For violin, viola, cello, and double bass Duration: approximately 10–12 minutes Emmoni (Obsession) is a chamber music composition for string quartet consisting of violin, viola, cello, and double bass. The work is constructed from a limited set of five pitches (A–E), creating an atmosphere of psychological tension and persistent unease. The inspiration for the piece came from a deeply personal experience: watching my uncle suffer from head cancer and witnessing the intense pain he endured as he held his head. This image remained fixed in my mind and led to the concept of Emmoni—an obsessive musical idea developed through the deliberate restriction of musical material to only five notes. The constant return to this limited pitch set reflects the nature of obsession itself: repetitive, inescapable, and emotionally charged. In the final measure, the music comes to an abrupt stop, symbolizing death and the moment when the soul leaves the body. Emmoni was performed and received an award at the Athens Concert Hall in 2008 under the direction of Theodore Antoniou.
