This toccata is based on the introit to the Christian Epiphany festival and solemnly announces the appearance of the Lord. As a toccata, the work is an introduction to Hakim's Adoration (Schott, ED 22614) for voice, flute and organ, a paraphrase of the first three introitus to Epiphany.
The Toccata develops a series of symphonic variations with virtuoso movements that emphasize the expressiveness of the words of the Gregorian text: Ecce advenit dominator dominus: et regnum in manu ejus, et potestas, et empium. Deus, judicium tuum regi da: et justitiam tuam Filio regis. ( Behold, the Lord, the ruler, comes: and the kingdom is in his hand, and the power and the dominion. God, give your judicial office to the king: and yours Justice to the son of the king. )(Malachi 3: 1, I Chronicles 29:12, Psalm 71: 1, 10, 11).
