One would say, how can such piercing beauty exist in this world? This choral composition is by Morten Lauridsen, an American (!) composer. There goes my hypothesis that all things beautiful come from the Old land.

The title of this piece is Dirait-on, which means ‘one would say’.  It is a part of the poem Les chansons des roses by the German poet Rainer Maria Rilke.  Lauridsen set this poem to choral composition.
