Guillaume-Antoine Calvière was a virtuoso French musician who was for many years organist of the Cathedral of Notre Dame de Paris.
Calvière was an admirer of François Couperin. His work included motets and pieces for organ. His Te Deum mimicked the sounds of wind and thunder. But apart from a short piece preserved in the library of the Brussels Conservatory, almost nothing has survived. After his death his widow gave his manuscripts to Louis-Claude Daquin for editing and publication. Daquin, his friend, colleague and also rival, neglected to do so. In fairness, Daquin failed to publish many of his own works.
