the <title> tag sets the title of the page so
<head><title> this is my page</title></head>
that will give your page the title of "this is my page". It doesn't put anything on the page just a title for the page, it's for your users and most importantly google and other search engines. For an actual page title you can use lots of different things, <p><h1>, etc etc
<p class="page-title" title="this is my title">this is my title</p>
that will give you some text that will allow you to hover over and a tooltip to pop up with the text within the title="" bit.
I am slightly confused as to what you want, but I think you want the second example.
