This is poetry stuff i am pretty good at poetry but this stumped me could really use some

the lamb

little lamb, who made thee?
does thou know who made thee,
gave thee life, and bid thee feed
by the stream and o'er the mead;
gave thee clothing of delight,
softest clothing, woolly, bright;
gave thee such a tender voice,
making all the vales rejoice?
little lamb, who made thee?
does thou know who made thee?
little lamb, i'll tell thee;
little lamb, i'll tell thee:
he is called by thy name,
for he calls himself a lamb.
he is meek, and he is mild,
he became a little child.
i a child, and thou a lamb,
we are called by his name.
little lamb, god bless thee!
little lamb, god bless thee!

the tyger

tiger, tiger, burning brigh
in the forests of the night,
what immortal hand or eye
could frame thy fearful symmetry?
in what distant deeps or skies
burnt the fire of thine eyes?
on what wings dare he aspire?
what the hand dare seize the fire?
and what shoulder and what art
could twist the sinews of thy heart?
and, when thy heart began to beat,
what dread hand and what dread feet?
what the hammer? what the chain?
in what furnace was thy brain?
what the anvil? what dread grasp
dare its deadly terrors clasp?
when the stars threw down their spears,
and watered heaven with their tears,
did he smile his work to see?
did he who made the lamb make thee?
tiger, tiger, burning bright
in the forests of the night,
what immortal hand or eye
dare frame thy fearful symmetry.

based on tone, why is it fitting that "the tyger" is featured in a volume titled, songs of experience?
