This is a relatively short Tennyson poem and, like many, is written in first person. Tennyson uses imagery of the valley, the water and the rocks to transport the reader into the speaker’s head. The speaker is obsessed with the voices in his head. I do not mean this in a crazy or about to be committed way. Nevertheless, by making the sounds of nature real for the reader, Tennyson is able to relay the speaker’s reality (“The voice of the dead was a living voice to me”).
