The songlike nature of “the lamb” and “the tyger” is enhanced by the refrain of these lines: and a) he became a little child. / i a child, & thou a lamb, b) little lamb, who made thee? / does thou know who made thee? c) tyger! tyger! burning bright / in the forests of the night, d) did he who made the lamb make thee? / tyger! tyger! burning bright
