Is it possible to have posts under pages?

Like otherwise i will have to edit the same post for each page, (each tab on the tab bar is just a page) – (except for the ‘home’ tab is not a page – see site will make it clearer)

So instead can I make more than one post under the tabs / pages, listed as ‘music suggestions’ ‘music festivals’ and ‘music reviews’ on the site, like is it possible to that? will make everything so much better and easier, thanks alot!
