How do the two stanza contrast with each other
Answers
Stanzas can be of any number of lines. Some types of stanza have special names. For example:
a couplet has two lines that rhyme with each other
a quatrain has four lines, rhyming in any pattern
The lines in rhyming stanzas can be of any length. However, it is quite common for them to be isometric, that is, for each of them to contain the same number of syllables. The stanza above by James Elroy Flecker is in regular eight-syllable lines: octosyllabics. By contrast, the stanza by Charlotte Mew is heterometric, meaning that the lines are of different lengths; in this case, of six, seven, eight and ten syllables.
It is common, but not at all essential, for all the stanzas in a poem to follow the same pattern with regard to:
rhyme scheme
number of lines
the lengths of the lines in corresponding positions (for instance, first or last within the stanza)
