(Vocal). Etre heureux ou ne pas l'etre (To be happy or not to be) is a collection of three songs for tenor and piano by Isabelle Aboulker on texts by Pierre de Ronsard, Jean de La Fontaine and Octave Mirbeau. "To the deep despair of Octave Mirbeau in front of a landscape of mountains, I opposed the smiling philosophy of Jean de La Fontaine and the lesson of happiness of Pierre de Ronsard. 'To be happy or not to be, ' an embarrassing question to which the music responds in a beautiful way." (Isabelle Aboulker)
