sentences:  Hypermnestra's soprano, which dominates the opera in a manner that anticipates the soprano-centered opera of Luigi Cherubini and Gaspare Spontini, is technically well written, but, typical of the opera as a whole, Salieri often seemed incapable of developing the basic material beyond the formulas inherited from Gluck.But the fine soprano role, the tremendously grim finale, and the brevity of "Les Danaïdes" (ten minutes under two hours) have ensured that the opera has made it onto CD.Salieri was certainly aware of his role in continuing the Gluckian tradition of the "tragédie lyrique", with the attention to the relationship between text and music.
