Deterritorialize the ritornello or invest the ear Resonance between music and philosophy in the thought of Gilles Deleuze

The present text addresses the relationship between philosophy and music at the thought of Gilles Deleuze. They are certainly the great musicians who can best talk about music, better talk about what they do. But speaking become anything other than musicians, become philosophers. Thus, inhabiting this outside of philosophy, Deleuze is immersed in music making it a resource for creating the concept of ritornelo. Through ritornelo philosophy it is in an active and interior alliance with the force that outside think that is music. Maintaining a relationship of exchange and resonance that does not stop interfering while developing their own way.
