Ego sum qui sum

Orlando di Lasso's motet Ego sum qui sum is a powerful setting of Latin scriptural text for SAATBB voices. The first part of the text, drawn from scripture, declares "I am who I am" and contrasts the righteous with the wicked, affirming a devotion to God's law. The subsequent passage describes a state of spiritual rest followed by a hopeful awakening, "for the Lord has sustained me." This sacred motet, a cornerstone of Renaissance polyphony, offers rich harmonic textures and contrapuntal interest, making it a compelling choice for discerning choirs. Its careful construction and expressive text painting provide ample opportunity for profound musical interpretation and a deeply moving performance.
