The final act is split into two . In the first, Thésée expresses his remorse for his treatment of Hippolyte and recounts Phèdre's suicide. In the words of Cuthbert Girdlestone, "it is a passionate, despairing "scena" with no fixed form". The scene shifts as Aricie is transported to be reunited with the resurrected Hippolyte in a beautiful rural landscape. This allowed Rameau to paint the scene using the techniques of pastoral music, including a musette (a type of bagpipe). He also displayed his orchestral skill in a chaconne, another feature of many of his later operas. The composer made a concession to popular taste by inserting the "Nightingale aria" () before the final gavottes. It is an example of an , the French term for a long in the Italian style, with the aim of showing off the singer's technical prowess. This particular specimen has no connection with the action of the drama, something Rameau would change with he wrote later, such as "Que ce séjour est agréable" and "Aux langueurs d'Apollon Daphné se refusa" in "Platée".
