Final answer:
The ballad is the type of poetry that tells a story of romance or adventure and is most suitable for singing, with its quatrains and alternating rhythmic lines that make it melodious and easy to sing.
Step-by-step explanation:
Among the types of poetry that tell a story of romance or adventure and are suitable for singing, the ballad is the most appropriate. With its origins in oral tradition, ballads were used to convey stories across generations, often accompanied by musical instruments. The ballad typically consists of quatrains, or four-line stanzas, and employs a simple rhyme scheme like ABCB, making it melodious and easy to sing. The lines of a ballad alternate in length, with the first and third lines being longer, commonly written in iambic tetrameter, and the second and fourth lines shorter, typically in iambic trimeter. This rhythmic structure is designed to convey the emotional content of the story, be it tragic, romantic or adventurous.
In contrast, a sonnet is a 14-line poem with a turn in thought and is not usually intended for singing. Other forms, such as the haiku with its 17 syllables, and the limerick with its humorous five-line structure, also do not generally fit the criteria for storytelling poems suitable for singing.
