Analysis of There is an hour, a pensive hour

THERE is an hour, a pensive hour;
(And oh! how dear its soothing pow'r!)
It is, when twilight spreads her veil,
And steals along the silent dale;
'Tis when the fading blossoms close,
When all is silence and repose;
Then memory wakes, and loves to mourn,
For days—that never shall return!

There is a strain, a plaintive strain,
The source of joy and yet of pain;
It is the song, whose dying measure,
Some friend belov'd has heard with pleasure;
Some friend—who ne'er again may hear,
The melting lay, to memory dear;
Ah! then, her magic spells restore,
Visions of blissful days no more!

There is a tear of sweet relief,
A tear—of rapture and of grief;
The feeling heart alone can know
What soft emotions bid it flow!
It is when memory charms the mind,
With tender images refin'd;
'Tis when her balmy spells restore,
Departed friends, and joys no more!
