The poet follows a special methods and techniques for instance: Alliteration, simile, personification, metaphor and so on.
Those tools are called: figures of speech.

Simile: is a word or phrase that compares something to something else using the words (as, like).
e.g. a face like mask.
white as snow.

Alliteration: The use of the same letter or sound at the same beginning of the words that are close together.
e.g. sing a song of sixpence.

Metaphor: Away of describing s.th by comparing it to s.th else which has the same qualities (but without the words as, like).e.g. {sb is a parrot} you express the fact that the person just repeats things without thinking.

Personification: The practice of representing objects, qualities…etc as humans.

 
e.g. The moon is terribly upset.
Upset is a human quality, a human attribute, so the poet here tries to personify the moon.

 
Draw in thy beams, and humble all thy might,
To that sweet yoke, where lasting freedoms be:
''sweet yoke'' It is paradox.
'' yoke'' is a symbol of imprisonment. Sweetness refers to pleasure and man can't be in prison and feel well in the same time.

 
Alas so all thinges nowe doe holde their Peace.
Heaven and earth disturbed in nothing:
The beastes, the ayer, the brides their song do cease:
The nightes chare the stares about do the bring:
Calme is the Sea, the waves worke lesse and lesse:
So am not I, whom love alas doth wring,
Bringing before my face the great encrease
Of my desires, whereat I wepe and syng,
In joye and wo, as in a doutfull ease.
For my swete thoughtes sometime do pleasure bring:
But by and by the cause of my disease
Geves me a pang, that inwardly dothe sting,
When that I thinke what greife it is againe,
To live and lacke the thing should ridde my paine.
