Cipriano de Rore was a Renaissance composer from the Franco-Flemish school, known for expressive madrigals and sacred music. He advanced chromaticism, text expression, and contrapuntal complexity, influencing Italian madrigal composition and shaping the emotional depth of 16th-century European music.

De Rore’s "O sonno, o vita" (also known as Ov’è, o silenzio) is a madrigal displaying expressive text painting, intricate polyphony, and chromatic harmony. It captures emotional tension, blending Renaissance artistry with intimate, dramatic reflection on sleep, life, and silence.
