Rhythm

definition: the effect produced in a play, film, novel, etc., by the combination or arrangement of formal elements, as length of scenes, speech and description, timing, or recurrent themes, to create movement, tension, and emotional value in the development of the plot.

example:The wind in her hair over there
The chair that sat with her hair
Eyes on eyes
Fire and lye
in the river sky on I

sentence: it is important because poems are all about beat and having a flowing, spiritual story told through your heart and rhythm and rhymes help keep a beat and help make poems flow more easily which makes the listener more attentive to your poems.

Onomatopoeia

definition: the use of imitative and naturally suggestive words for rhetorical, dramatic, or poetic effect.

example:

• splash
• spray
• sprinkle
• drip
• drizzle

sentence: it uses natural words to give a poem a effect so that is why it is important

imagery

definition: the formation of mental images,  figures, or likenesses of things, or of such images  collectively: the dim imagery of a dream.

example:

The winter evening settles down

With smell of steaks in passageways.

Six o'clock.

The burnt-out ends of smoky days.

And now a gusty shower wraps

The grimy scraps

Of withered leaves about your feet

And newspapers from vacant lots;

The showers beat

On broken blinds and chimney-pots,

And at the corner of the street

A lonely cab-horse steams and stamps.

And then the lighting of the lamps.

sentence: it is important because it inspires feeling

Personification

definition: the attribution of a personal nature or character to inanimate objects or abstract notions, especially as a rhetorical figure.

example:Hey diddle, Diddle,

Sentence:Consider the vulgarity of objectification. Personification must be its opposite: imagining that even an ash tray is worried about second hand smoke is the very stepping beyond the present and into the fantastic and literary that poetry promises.
Authors use personification to make stories/ poems more dramatic and interesting or to convey a certain mood. Personification also helps us to relate more to the object or idea that is being personified because it is easier for us to relate to something with human attributes.
Basically, personification is an inanimate object doing something that only an organism can do. ex. The rival flower (inanimate object) slowly pulled out his gun. (flowers don't have hands or guns!)
another example would be, The flowers are dancing in the wind.

Simile

definition: a figure of speech in which two unlike things are explicitly compared, as in “she is like a rose.”

Example:  “cute as a kitten,” comparing the way someone looks to the way a
kitten looks


sentence: simile is important because we always use it and they always start with like or as
 

repetition

definition: continuously saying the same thing

example:

I'm nobody! Who are you?
Are you nobody too?
Then there's a pair of us-don't tell!
They'd banish us you know.

How dreary to be somebody!
how public, like a frog.
To tell your name livelong day
To an admiring bog!

significance:so you can understand it 

tone

definition: your emotions expressed in a way when you  read a poem

example

I'm going out to clean the pasture spring; (light, informing tone)
I'll only stop to rake the leaves away ("only" tone - reservation)
(And wait to watch the water clear, I may): (supplementary, possibility)
I sha'n't be gone long. -- You come too. (free tone, assuring) (after thought, inviting) "Rather well for me" --

I'm going out to fetch the little calf (Similar, free, persuasive, assuring
That's standing by the mother. It's so young, and inviting tones in second stanza)
It totters when she licks it with her tongue.
I sha'n't be gone long. -- You come too.


significance:the quality and the pitch in a poem
