Are most ballads written in four to six line stanzas?

It's not accurate to say that most ballads are written in four to six line stanzas. While some ballads do follow this pattern, ballad stanzas can vary greatly in length and structure.

Here are some important points to consider:

* Traditional ballads: These are often characterized by quatrains (four-line stanzas), with an ABCB rhyme scheme. However, even within this tradition, there's variation. Some ballads may have longer stanzas or a different rhyme scheme.

* Modern ballads: Contemporary ballads often break free from traditional structures. They can have any number of lines per stanza, varying rhyme schemes, or no rhyme at all.

* Ballad structure is fluid: Even in traditional ballads, the stanza length might change within the poem for artistic effect.

Therefore, focusing on a specific number of lines per stanza for all ballads isn't the best approach. It's more important to understand the characteristics and conventions of different ballad types, and to recognize the artistic choices made by individual poets when writing ballads.
