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.
Birds inspire and uplift us with their carols... In the muslc of both birds and humans, beauty is "the wine which overflows." When the last lark has fallen silent, something holy will have vanished from the world. The chorus of life will be muted. The cathedral of the earth will have lost its choir.
