Newbie:- show posts with specific tags on seperate page

Hi,
I am just about learning to use WP.
I was able to import my poetry blog & personal from blogger to wordpress
& I was also able to tag the posts from the poetry blogs as “Poetry” using the bulk edit option.

I have created a new page “Poems”

Now, I would like to show all of my “Poetry”= tagged posts at the “Poems – Page”

Do i have to edit each post individually & instruct to display in “Poems page”–
OR, is there some kind of script / function that tells
Function ( tagname , pagename) … and does the ordering automatically.

( Please provide link tutorials .. i can really use them)

Thanks in advance,
Regards.
