This work was written in December, 1986, for a recital given by Hakim and his wife, Marie-Bernadette Dufourcet, at the Sacré-Cœur. It is conceived as a duo, using the Grand Organ and Choir Organ in the Basilica. This antiphonal use of the organs is interpreted by the former Rector of the Sacré-Cœur, Father François de Vorges, as a ''dialogue between God and his faithful people, recalling the dialogue of the angels and shepherds''. The theme and variations form of the Fantaisie lends itself very successfully to this well-known Christmas hymn.
