跪求～～丁尼生的一片诗歌。come down, o maid的赏析

There is sweet music here that softer falls
Than petals from blown roses on the grass,
Or night-dews on still waters between walls
Of shadowy granite,in a gleaming pass;
Musiccthat gentlier on the spirit lies,
Than tiered eyelids upon tired eyes;
Music taht brings sweet sleep down from the blissful skies.
