Analysis of The Wind that Shakes the Barley

There's music in my heart all day,
I hear it late and early,
It comes from fields are far away,
The wind that shakes the barley.

Above the uplands drenched with dew
The sky hangs soft and pearly,
An emerald world is listening to
The wind that shakes the barley.

Above the bluest mountain crest
The lark is singing rarely,
It rocks the singer into rest,
The wind that shakes the barley.

Oh, still through summers and through springs
It calls me late and early.
Come home, come home, come home, it sings,
The wind that shakes the barley.
