Prayer begins in us the restoration of the divine image, in all its hiddenness and wonder. It brings us closer to the "region of likeness" and every prayer is an act of letting the old self go. It involves "dying". The grain of wheat falls into the ground and dies. Dead, it is destined to bear much fruit.
Music is sound AND silence. It is the spaces BETWEEN the notes that create rhythm, melody, and meaning, and the greater the composer -- and the perfornance -- the better the quality of the silence. Legendary pianist Artur Schnabel said that it wasn't the notes but the silences between them he played better than other people. A few seconds more or less at crucial moments in the performance of a piece may mean the difference between a mundane and a transcendent experience.
