Some of the forms used in poetry can be somewhat daunting, especially for beginners.
Percy Bysshe Shelley had no difficulty when he wrote his famous Ode to the West Wind, for he used a form known as the terza rima. Each stanza of this has three lines, usually in iambic pentameter, although nowadays poets do not always use this. These stanzas, known as tercets, have a pattern of chain rhyming, which is: aba bcb cdc ded efe, etc.
