The unknown story of a restrained passion.

History remembers Jean-Jacques Rousseau as an Enlightenment philosopher, brilliant co-author of the « Encyclopédie », a thinker who inspired the French Republic. But Music was Rousseau's first and foremost passion, and he sought to be recognised as a musician. Music was dear to him all throughout his life. He worked as a choir master, composer, musician, musical theorist, and he often copied music to make a living. On the tercentenary of his birth, we offer a rediscovery of this historic figure from a new angle: Rousseau, a successful composer who, in his own way, deeply influenced the course of European and international musical aesthetics.
