This thought by Henri Dutilleux is enough to understand the spirit behind his L'arbre des songes ("The Tree of Dreams"), a Violin Concerto that, in this programme, fits perfectly with Richard Wagner's Waldweben, from Siegfried, the music that accompanies a silent reverie during which the protagonist listens to the murmurs of the forest and the singing of a bird perched on a tree. It is about the refreshment that nature offers to all of us, disctracting us for a moment from the frenzy of our vicissitudes, and which brings us into a state of contemplation in which, suddenly, we feel happy.
