This excellent poem from Blake's monumental Songs of Innocence and Experience is perhaps one of his most powerful works as it focuses on the tiger of the title as an amazing symbol of energy, power and strength. The speaker is so impressed by the tiger that the speaker, in a series of questions, asks what immortal being, divine or demonic, could have possibly fashioned such a fearsome and awe-inspiring creature, and how. It is most appropriate then to describe the tone of this poem as one of awe and wonder, as the speaker contemplates the majesty of the tiger and wonders about its true source. Consider the following stanza:
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?
The relentless questioning that carries on throughout the poem combined with the admiration and also fear that the tiger obviously inspires in the speaker, and his curiosity as to the precise origin of such a beast, establishes the tone of wonder and awe that dominates the poem.
