Writing tercet and triad poetry

Tercet Stanzas

The tercet is a poetry form with Italian roots. One of the most famous examples of the form is Dante’s The Divine Comedy (aff). At heart, this is a stanza form more than a form for a complete poem. In most cases, multiple stanzas are combined to create a single poem. The poem may be be a string of several tercets. In other cases, the tercet is one component in a poem composed of other stanzas such as couplets or quatrains.

The Divine Comedy was composed of three line stanzas. Every first and third line ends with a rhyme. This is the classic version of the form. It is a three-lined poetic stanza in which the first and third lines rhyme. The second line is blank (unrhymed) verse.

Today, we call this rhymed form an enclosed tercet because the two rhymed lines enclose the blank line. Most modern tercets employ unrhymed or blank verse. An even more stringent form of the tercet is the Sicilian Tercet. The Sicilian Tercet incorporates the enclosed form, but also requires that the poet write in iambic pentameter.

The tercet is rarely a complete poem in itself. Instead, poets write multiple stanzas to create longer works. A famous English example of a poem using tercet stanzas is Percy Shelley’s Ode to the West Wind, which includes:

The winged seeds, where they lie cold and low,
Each like a corpse within its grave, until
Thine azure sister of the Spring shall blow


The triad is a specific form of tercet. The origins of the triad are Irish and Welsh. A triad is a poem composed of three tercets. It is a consideration of three things and their effect on a person. Welsh versions of the Arthurian legends make heavy use of this form.

Here is a sample triad that I have written:

Cold Comfort

My favorite glass folds upward.
Three curved echoes.
Growing large enough to hold comfort.

My blender can spin ice to powder.
Gentle as snow in my hair.
Eager to provide relief.

Parrot Bay and pina colada mix.
Turn snow to sweet cold liquor.
And I can smile now.

The triad is one of the lesser know poetry forms, but it is an enjoyable outlet for expression. You can add as much challenge as you wish. You can simply write in three-line stanzas or you can use iambic pentameter and enclosed tercets if you wish to increase the writing challenge.
