aabb

Tyger! Tyger! burning bright

In the forests of the night,

What immortal hand or eye

Could frame thy fearful symmetry?

abab

"The wind doth blow today, my love

And a few small drops of rain;

I never had but one true-love

In cold grave she was lain.

abba

Strong Son of God, immortal Love,

Whom we, that have not seen thy face,

By faith, and faith alone, embrace,

Believing where we cannot prove;

abcb

There lived a wife at Usher's Well,

And a wealthy wife was she;

She had three stout and stalwart sons,

And sent them over the sea.

aaba

Awake! for Morning in the Bowl of Night,

Has flung the Stone that puts the stars to flight:

And Lo! the Hunter of the East has caught

The Sultan's Turret in a Noose of light.
