This composition is based on a 12-tone row: C, G♯, D, F, A, E, F, B, G, D♯, A♯, C♯. The piece develops from this melody, with the piano introducing the theme while chords are formed from the same notes. The violin uses col legno technique, the clarinet enters with staccato, and the violoncello functions as a bass doubling the piano line. Throughout the piece, I applied compositional techniques such as retrograde, inversion, and transposition. Glissando and sustain were used to explore dynamics and harmonic texture, and the col legno technique adds a distinctive timbre and spiritual quality. This project allowed me to experiment with 12-tone writing in a free composition context.
