Here's a breakdown:
* Traditional Forms: Some poems adhere to strict structures with specific line counts per verse. For example, a sonnet has 14 lines divided into three quatrains (four-line stanzas) and a final couplet (two-line stanza).
* Free Verse: In free verse poetry, the poet has complete freedom to determine the length and structure of each verse.
So, to answer your question directly, there could be any number of lines in three verses, depending on the poem.
Examples:
* 3 verses of 4 lines each: 12 total lines
* 3 verses of 6 lines each: 18 total lines
* 3 verses of 2, 3, and 4 lines each: 9 total lines
The beauty of poetry lies in its flexibility!
