You knew Felix, but what do you know about Fanny? She was the elder sister of the composer of A Midsummer Night’s Dream, bathed like him in the society of the Enlightenment and the early Romantics, where she frequented Goethe and Heine, and was an admired pianist in their pres-tigious salons. However, her vocation as a composer was constantly thwarted by her family, which was nevertheless among the most enlightened of its time, and which considered that a decent woman could not embark on a public career without dis-honour. This was the fate of many female creators of the time, who were silenced, and whose works they nevertheless managed to write are now coming to light. With Felix et Fanny, Jérémie Rhorer and Le Cercle de l’Harmonie mirror the scores of the brother and sister, united as much by their mutual affection, despite the inequality established between them, as by their common passion for the theatre. Although neither of them ever wrote a complete opera, they set to music and songs the most beautiful plays of the European repertoire, from Shakespeare to Schiller and of course Goethe. And if the grace and fantasy of Felix remain irresistible, the modernism of Fanny, which sometimes seems to open the door to Wagner, will be a discovery for many.
