I'm up for a Sestina, difficult but not so that it slays its takers-on like mere peasants at the gate. Historically, the Sestina is a French form. initially from the work of Arnaut Daniel, one of the troubadours in the service of French nobles--12th century, in his poemThe Firm DesireBoth french and the English translation appear as an example in the link. The Sestina is an exercise in repetition, and is comprised of 6 sestets (six-line stanzas), and an ending tercet (three-line stanza) called an envoy. Thus the sestina has 39 lines in total. The six words ending each line of the first stanza are repeated, in a different order ending the lines in each of the remaining five stanzas. The repeated words are unrhymed!!! In the envoy, which is the closing tercet (three-line stanza) each of the six words are used, with one in the middle of each line and one at the end of each line. The Pattern is as follows. Stanza 1: 1, 2, 3, 4, 5, 6 Stanza 2: 6, 1, 5, 2, 4, 3 Stanza 3: 3, 6, 4, 1, 2, 5 Stanza 4: 5, 3, 2, 6, 1, 4 Stanza 5: 4, 5, 1, 3, 6, 2 Stanza 6: 2, 4, 6, 5, 3, 1 Envoi: Middle words 2, 6, 4, End words 5, 3, 1 the order of these can be varied but all six words must be used, two words in each line. You can either choose your six end words first or compose the first six line stanza freely and use its end words as a guide, which I find much easier. Either way, theSestina Generator will compile an ordered placement list of your chosen end words that you can follow for each sestet as well the envoy.
