What is the Definition of tetrastich?

A tetrastich is a four-line stanza in poetry. It's a basic unit of verse that can be found in various poetic forms.

Here are some key points about tetrastich:

* Structure: It's a very simple structure, consisting of exactly four lines.

* Rhythm and Rhyme: While there are no specific rules for rhyme or rhythm, some tetrastichs follow patterns like AABB or ABAB.

* Usage: Tetrastichs are commonly used in:

* Haiku: A three-line form with a 5-7-5 syllable structure, often followed by a four-line tetrastich.

* Quatrain: A four-line stanza that's often part of longer poems like sonnets or ballads.

* Free Verse: Tetrastichs can also be used in free verse poetry, where there are no restrictions on rhyme or rhythm.

Example:

Here's a simple tetrastich:

> The sun dips low, a fiery glow,

> The clouds are painted, soft and slow.

> A gentle breeze whispers through the trees,

> As twilight falls, the world finds peace.

This example uses the AABB rhyme scheme, but tetrastichs can be written with any rhyme scheme or even without rhyme at all.
