In tribute to the Slavonic liturgy that I practiced with my Russian friends: a long evening of singing under the transparent gaze of icons with warm colours followed by the meal of Easter mix in my memories, not to forget the perennial tea in the samovar, Russian word meaning "boiling by itself." Is there a more simple image to symbolize this bubbling music of its intrinsic strength? In the second part, the colour of the two alti soli as hovering above the voices of men adds a filled tenderness lighting. It is for us and those who tend the ear that we sing without forgetting that "we sing for You".
