Sacred Renaissance hymn for the Annunciation (March 25th). A cappella male voices layered with ethereal female soprano emerging gradually — like light entering a dark chapel. Latin and Portuguese fragments. Gregorian chant foundation that evolves into polyphonic Renaissance harmony. Reverent, luminous, ascending. The sound of divine light touching human flesh. Organ drone underneath. 3 minutes. Ends in sustained resonance — the moment before the Word becomes flesh.
