Analysis of Now and then

“All life is built from song”
   In youth’s young morn I sang;
And from a top-near hill
   The echo broke and rang.

The years with pinions swift
   To youth’s high noon made flight,
“All life is built from song”
   I sang amid the fight.

To life’s sun-setting years,
   My feet have come—Alas!
And through its hopes and fears
   Again I shall not pass.

The lusty song my youth
   With high-heart ardor sang
Is but a tinkling sound—
   A cymbal’s empty clang.

And now I sing, my Dear,
   With wisdom’s wiser heart,
“All life is built from love,
   And song is but a part.”
