"Jacobus Gallus' wide-ranging, eclectic style blended archaism and modernity. He rarely used the cantus firmus technique, preferring the then-new Venetian polychoral manner, yet he was equally conversant with earlier imitative techniques. Some of his chromatic transitions foreshadowed the breakup of modality; his five-voice motet Mirabile mysterium contains chromaticism worthy of Carlo Gesualdo."
