Dylan Thomas wanted his poetry to be read aloud.Discuss the poetic elements he used to make his work especially appealing when heard.

To answer this question, I'll use Thomas' poem "Do Not Go
Gentle into That Good Night," as this is a very well-known poem where Thomas speaks to
his dying father, telling him to die well and with with strength.  If you read that poem
aloud, there are several elements that aid its flow, rhythm and readability. I provided
a link below of the poem itself.

First of all, Dylan makes
great use of rhythm and rhyme. As you read the poem, it sounds like a song, with a
lilting bounce and roll to it.  He achieves this by using 10 syllables in each line;
this provices a parallel structure that sounds planned and even, balanced and
structured.  Then, he rhymes words in an ABA structure; the ends of the A lines rhyme. 
This makes it sound like a rap, or a song, as those tend to rhyme.  The rhythm and rhyme
gives the poem  an overall pleasing sound when read
aloud.

Another technique that makes his poetry work when
read aloud is the use of repetition.  Think of it this way--when you are at a concert,
and the chorus of the song arrives, the lead singer will often turn his mic to the
audience and you them sing it.  You guys know it, because it is repeated often, so are
able to anticpate and sing along with that chrous.  Thomas uses the same technique.  He
repeats the phrases "do not go gentle into that good night" and "rage, rage against the
dying of the light" at the end of the stanzas; the audience can anticpate it, and speak
along with him.  That adds an element of anticipation and participation on the part of
the audience, which is a nice effect.

Those three
elements--rhythm, rhyme, and repetition--are all poetic elements that make Thomas'
poetry great for reading aloud.  I hope that those thoughts helped; good
luck!
