\begin{verse} line1 \\ line2 \\ ... \end{verse}
The verse
environment is designed for poetry, though you may find
other uses for it.
The margins are indented on the left and the right, paragraphs are not
indented, and the text is not justified. Separate the lines of each
stanza with \\
, and use one or more blank lines to separate the
stanzas.
