I had this posted in a different thread and had some wonderful responses there so thought that I should post in a new thread in case anybody else wanted to give it a go or wanted to read peoples attempts.
A trenta-sei consists of six (6) stanzas, each with six (6) lines, for a total of 36 lines in the entire poem (hence, the name of the form). The first stanza, to some degree, controls each of the stanzas that follows it, in this fashion: The second line of the first stanza becomes the first line of the second stanza, the third line of the first stanza becomes the first line of the third stanza, the fourth line of the first stanza becomes the first line of the fourth stanza, the fifth line of the first stanza becomes the first line of the fifth stanza, and the sixth line of the first stanza becomes the first line of the sixth stanza. In other words, the schematic looks like this:
Schematic: Repetition scheme:
123456
2xxxxx
3xxxxx
4xxxxx
5xxxxx
6xxxxx
The trenta-sei also has a rhyme scheme which is ababcc.
