The choir organ of Notre-Dame de Paris Cathedral is an instrument of 30 games distributed on two keyboards and a pedal.
Its history begins at the beginning of the nineteenth century, in the aftermath of the revolution, when the "fashion" of the chorus organs spreads into the churches to overcome the lack of musicians of the cult. Instrument of the heart of the Cathedral liturgy, he has been the object of great care since his origins in the image of the talent of the organists who have succeeded.
Taking an important part in the musical device of Notre-Dame de Paris, the choir organ performs several functions made possible thanks to the richness and diversity of its sound palette. For the daily offices of the week during which he intervenes alone, he is sometimes a soloist, sometimes an accompanist, supporting the Cantor or the assembly. On weekends or in exceptional ceremonies, he alternates with the great organ for dialogue between the singing of the crowd and the singing from the choir. It can be said that he is also the instrument of the Christians of the island of the city, expressing their joys and sorrows to the various celebrations. Finally, he is the privileged and faithful partner of the cathedral's mastery, be it for the numerous concerts and recordings where his presence is necessary as for the offices where the choir and organ unite their voices to sing the glory of God.
From April 1989 to December 1992, during the restoration of the great organ, it was the only instrument of Notre-Dame; many organists of passage in Paris confessed then to the holder, Yves castagnate, how much they would have wished to have such an instrument... In the Tribune!
