Danielle Ribouillault wrote in Les Cahiers de la Guitare on his teaching: "As I entered the class, he explaines how to use the notes to revive a phrase.. and then you can hear how the phrase flourishes and starts to live. He orientates the student to a generous Rubato that lets the melody vibrate. He, who had played with such a musicality and mastery, knows how to transmit his live-giving esprit… A lot of students attended his class: clearly because something strong happens with him during his passionate transmission of music, something essential and more intense than otherwise.“
