Terza Rima

Three lines per stanza.
The first and third lines rhyme with each other in each stanza.
In the second and subsequent stanzas, the rhyme of the first and third lines also rhyme with the second
line of the previous stanza.
The resulting chain of rhymes has this pattern:
a-b-a,
b-c-b,
c-d-c,
etc.

Unlimited number of stanzas.
The poems may end with a single line or with a couplet that rhymes with the second line of the final tercet.
Any rhythm may be use.

For this activity, you will have four stanzas.
