When we study the speech figures, we learned that this resource is widely used in literary texts to give more expressiveness to the language, that is, to make the text prettier and even more poetic. For this, we use metaphors to play with words and their meanings, making the text much more interesting!
There are also, to help us beautify our writing, the so-called figures of style, among them, the sound figures. These, in turn, make an interesting and pleasant combination of words and sounds and are divided into four types: Alliteration, assonance, paronomasia and onomatopoeia. The names are complicated, but when sound figures are present in a text, it becomes extremely musical, immediately captivating our sympathy. See just some examples of sound pictures:

Alliteration repeats consonants or phonemes to make the text more intense
here comes the duck
Paw here, paw there
here comes the duck
To see what's there
(The duck - Vinicius de Moraes)
In the music of Vinicius de Moraes, we have a clear example of the sound figure alliteration, because the phoneme /pa/ was repeated to make the text very musical. Now know an example of assonance, sound figure that repeats the sounds of vowels:
Assonance is the repetition of identical vowel sounds
weird lollipop
I've never seen such a thing
It has everything kind
I want one of these for myself.
(weird lollipop – Kleiton and Kledir)
already the paranomasia brings together in the same sentence words almost identical in sound, but with different meanings:
Paranomasia brings together in the same sentence words with similar sounds but different meanings
Guys, I'm getting impatient
my hunger is persistent
eat cold eat hot
eat what you see ahead
eat the tongue eat the tooth
anything that feeds
Hunger simply eats.
(Hunger Eat – Sung Word)
To finish our sound figures, know an example of onomatopoeia, which are the words that imitate the sounds of what they represent:
An onomatopoeia is a word whose sound roughly mimics the sound of what it means.
pass, time, tick-tock
Tic-tock, pass, time
Come soon, tick-tock
Tic-tock, and go away
Hobby
very quickly
do not delay
don't delay
that I'm already
Very tired
I've lost
all the joy
to do
my tick-tock
Day and night
Night and day
TIC Tac
TIC Tac
Day and night
Night and day.
(The clock - Vinicius de Moraes)
