🎹 Sonata in C# Minor, Moonlight Piano
🎭 Emotional Character
Written packed with overlapping ideas and simultaneous motion, this piece feels unsettled and urgent, as if something important has been left undone, driven and urgent, refusing to slow down and with a full but measured voice, shaped by bold swells and sudden retreats of sound.
