agree with Johnathon, poetry will help to get the rythmn, but  `accent` is what makes us all individuals 

It's not something you can get from a book - you'd need a real native speaker with lots of patience, who will listen to you and give you advice on sounding natural.

Songs and videos will give you a straing point, but you do need real feedback.

Hi

Why dont you try some simple childrens poems, that would give you an idea of the 'beat' of the language.

Thanks for all your good advice. :)

  Sean:

 It is a common misconception amongst  students of English,  that they need to eliminate their accent.

That is false.   Accents are entirely acceptable.  Many English speaking countries are "melting pots" of foreign   people who speak English with an Accent.  There are German accents  Spanish accents, 

Slavic accents, Italian Accents,  French Accents,   African accents,  Indian  accents, Chinese Accents,  Vietnamese accents,  Cambodian Accents,   Arabic accents and so on and so forth.

  You can find rythm for the English language in Nursery Rhymes,  Poems,   and songs generally.

   Here is a link to the Slow Ballads that I recommend for this kind of study.

You can also find  in my Notebook Entries, lyrics (words) for all of these songs, and for many others  I recommend for study.  The Slow Balldads are the easist to understand.
