These are the ingredients for a poem. But like all recipes, you don't need every ingredient every time:

MUSIC
- beat, rhythm & rhyme
IMAGERY
- pictures painted
IMAGINATION
- describing what's not there.

STORY
- the narrative, the journey within the poem
STRUCTURE
- size & shape (line breaks and stanzas)

Also, you may have a inclination to use a particular ingredient to the exclusion of others - so as you recognise this, experiment with those ingredients which you are less confident about using.

Note
- the first three are where poets typically find their freedom to explore ideas within the poem;
- the last two are where the reader typically finds handholds / the anchor to better engage with the poem.
