The poem has open-ended questions that require the reader to think about the solutions. Unfortunately, the questions are unanswerable for the reader. Given that Blake wants the reader to think about the formation of the "tyger," one may easily believe that Blake is the speaker. However, since the poem is written in iambic pentameter, it cannot be said who the speaker is with certainty. According to most commentators, the poem is not meant to have a single clear-cut answer but many possible interpretations. As such, no single person can be said to be its speaker; instead, the poem itself can be said to speak through its use of dramatic irony. In other words, although the poem appears to be describing actual events that took place in Blake's life, it is actually doing so as allegory. For example, when the "Tyger" kills its master, it is punished by being chained up and set adrift on the ocean. But since this incident takes place before dawn, when it is dark, none of the bystanders can see this punishment. Thus, they believe that the "Tyger" must have escaped from someone else who lived in Southwark at the time or perhaps even long after. Another interpretation believes that the poem is speaking directly to its audience and asking them questions about their lives.
