 It probably was owing to pressure on Molière exerted by Mlle de Guise and by young Mme de Guise that the playwright took the commission for incidental music for "Le Malade imaginaire" away from Dassoucy and gave it to Charpentier.After Molière's death in 1673, Charpentier continued to write for the playwright's successors, Thomas Corneille and Jean Donneau de Visé.Play after play, he would compose pieces that demanded more musicians than the number authorized by Lully's monopoly over theatrical music.
