A tambourin from its prologue would be used by the composer in his Pièces de clavecin en concerts, but much of the prologue was changed in the opera's revival along with the introduction of Cléone.  One unmelodic chorus in this opera is 'Brisons tous nos fers' which is sung by demons, while Chromatic ritornellos characterize another chorus of 'Que tout gémisse'.   In act 4, one of  title characters sings ‘Séjour de l'éternelle paix' while in pain of being alone, and another title character earlier sings ‘Nature, Amour, qui partage mon coeur'. In act 5 a planet sings 'Brillez, astres nouveaux' about the fates of the title characters, but its most famous aria is (*) Tristes apprêts, sung by Telaira over the loss of her loved one.  For ten points identify this Tragédie en musique with libretto by Pierre-Joseph Bernard and music by Jean-Philippe Rameau about the Gemini twins.
