Gilles Jullien
He is credited with bringing the style of French organ music then current in Paris to Chartres.
[citation needed] All of Jullien's surviving music is contained in his Premier Livre d'orgue (Paris, 1690).
According to the preface, these works were intended for liturgical use, but the only link to the liturgy is a fugue on Ave maris stella.
One of these is that in the preface Jullien claims to have invented five-voice genres, even though such pieces appeared earlier, in collections by Nicolas Gigault and André Raison, published in the late 1680s.
Another vocal work by Jullien, La Crèche de Bethléem, is known by name only, and the second organ book was apparently planned, but never appeared.
